[PATCH] spi: Fix mismatched DT property access types

[PATCH] spi: Fix mismatched DT property access types

[Rob Herring (Arm)]

The SPI drivers read properties whose bindings use normal uint32 cells.
Using boolean or u16 helpers makes the access look like a different DT
encoding and causes the property checker to flag the call sites.

Use presence checks for unsupported properties and read numeric cell
properties through u32 helpers before assigning to driver fields.
