Subject: [PATCH] ARM: dts: microchip: sama5d2: fix spi flexcom fifo size to 32

From: Nicolas Ferre <nicolas.ferre@...rochip.com>

Unlike standalone spi peripherals, on sama5d2, the flexcom spi have fifo
size of 32 data. Fix flexcom/spi nodes where this property is wrong.

Fixes: 6b9a3584c7ed ("ARM: dts: at91: sama5d2: Add missing flexcom definitions")
