ARM: dts: microchip: sama7d65: fix uart fifo size to 32
commit 1f591be0a02c697f65a21be35f1d74117bbf4be2 upstream.
On some flexcom nodes related to uart, the fifo sizes were wrong: fix
them to 32 data. Note that product datasheet is being reviewed to fix
inconsistency, but this value is validated by product's designers.
