[ Upstream commit 934e69669e32eb653234898424ae007bae2f636e ]

Enable the checksum option for these two endpoints in order to allow
mobile data to actually work. Without this, no packets seem to make it
through the IPA.

In the downstream IPA driver there's only one group defined for source
and destination, and the destination group doesn't have a _DPL suffix.

Commit b310de784bacd ("net: ipa: add IPA v4.7 support") was merged
despite an unresolved comment made by Konrad Dybcio.  Konrad
observed that the IMEM region specified for IPA v4.7 did not match
that used downstream for the SM7225 SoC.  In "lagoon.dtsi" present
in a Sony Xperia source tree, a ipa_smmu_ap node was defined with a
"qcom,additional-mapping" property that defined the IPA IMEM area
starting at offset 0x146a8000 (not 0x146a9000 that was committed).

The IPA v4.7 target system used for testing uses the SM7225 SoC, so
we'll adhere what the downstream code specifies is the address of
the IMEM region used for IPA.

Currently all platforms are assumed allot 8 routing table entries
for use by the modem.  Instead, add a new configuration data entry
that defines the number of modem routing table entries, and record
that in the IPA structure.

Some resource limits on IPA v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents the
IPA from booting properly. The limits are all 6 bits wide so
adjust the max values to 63.

The backward compatibility register (BCR) has a set of bit flags
that indicate ways in which the IPA hardware should operate in a
backward compatible way.  The register is not supported starting
with IPA v4.5, and where it is supported, defined bits all have the
same numeric value.

Redefine these flags using an enumerated type, with each member's
value representing the bit position that encodes it in the BCR.
This replaces all of the single-bit field masks previously defined.
