Subject: [PATCH v4 2/5] spi: cadence_qspi: Fix fdt read of
spi-max-frequency

Fix the fdt read for spi-max-frequency as it's contained
in the child node. Current state of code is always
returning default value.

Changes for v4
- use the newly created fdtdec_get_uint
Changes for v3
- Use of fdt_getprop_u32_default_node instead casting
Changes for v2
- Add unsigned casting for plat->max_hz
