Qcom SoCs require scaling the interconnect paths for proper working of the
peripherals connected through interconnects. Even for accessing the UFS
controller, someone should setup the interconnect paths. So far, the
bootloaders used to setup the interconnect paths before booting Linux as
they need to access the UFS storage for things like fetching boot firmware.
But with the advent of multi boot options, bootloader nowadays like in
SA8540p SoC do not setup the interconnect paths at all.
So trying to configure UFS in the absence of the interconnect path
configuration results in a boot crash.
To fix this issue, and also to dynamically scale the interconnects (UFS-DDR
and CPU-UFS), interconnect API support is added to the Qcom UFS driver.
With this support, the interconnect paths are scaled dynamically based on
the gear configuration.
During the early stage of ufs_qcom_init(), ufs_qcom_icc_init() will setup
the paths to max bandwidth to allow configuring the UFS registers. Touching
the registers without configuring the icc paths would result in a crash.
However, we don't really need to set max vote for the icc paths as any
minimal vote would suffice. But the max value would allow initialization to
be done faster. After init, the bandwidth will get updated using
ufs_qcom_icc_update_bw() based on the gear and lane configuration.
The bandwidth values defined in ufs_qcom_bw_table struct are taken from
Qcom downstream vendor devicetree source and are calculated as per the
UFS3.1 Spec, Section 6.4.1, HS Gear Rates. So it is fixed across platforms.

Devfreq uses the default DEVFREQ_TIMER_DEFERRABLE mode which uses the
deferred timer for scheduling the devfreq load monitor function. This
causes the load monitoring to be done only with non-idle CPUs and not
making use of the idle CPUs.
Hence, use the DEVFREQ_TIMER_DELAYED mode which uses the delayed timer
thereby making use of idle CPUs as well for load monitoring.

platform_msi_domain_alloc_irqs() does not always get consecutive IRQ

Now that there is a new dedicated ICE driver, drop the ufs-qcom-ice and use
the new ICE api provided by the Qualcomm soc driver ice. The platforms that
already have ICE support will use the API as library since there will not
be a devicetree node, but instead they have reg range. In this case, the
of_qcom_ice_get will return an ICE instance created for the consumer's
device. But if there are platforms that do not have ice reg in the consumer
devicetree node and instead provide a dedicated ICE devicetree node, the
of_qcom_ice_get will look up the device based on qcom,ice property and will
get the ICE instance registered by the probe function of the ice driver.
The ICE clock is now handle by the new driver. This is done by enabling it
on the creation of the ICE instance and then enabling/disabling it on UFS
runtime resume/suspend.

In preparation for adding MCQ error handler support, update the MCQ code to
use the ufshcd_mcq_poll_cqe_lock() in interrupt context instead of using
ufshcd_mcq_poll_cqe_nolock(). This is to keep synchronization between MCQ
interrupt and error handler contexts because both need to access the MCQ
hardware in separate contexts.

The newly added MSI support is mostly hidden inside of an #ifdef,
except for one line that now causes a build failure when MSI
is disabled:
drivers/ufs/host/ufs-qcom.c: In function 'ufs_qcom_remove':
drivers/ufs/host/ufs-qcom.c:1698:9: error: implicit declaration of function 'platform_msi_domain_free_irqs' [-Werror=i]
1698 | platform_msi_domain_free_irqs(hba->dev);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Above that, the symbol that guards the other call was recently removed, so
that is all dead code at the moment.
Remove the incorrect #ifdef and instead of a Kconfig dependency to only
allow building the driver when CONFIG_GENERIC_MSI_IRQ is enabled. This
symbol is always present when PCI_MSI or ARM_GIC_V3_ITS are enabled, both
of which should be present on kernels that can run on Qualcomm SoCs.
The 'select RESET_CONTROLLER' in combination with this dependency
unfortunately causes a dependency loop and this is a user-visible symbol,
so it's better to change both to 'depends on'.
