[PATCH 2/4] spi: cadence-xspi: put marvell support code under CONFIG_64BIT

[Jisheng Zhang <jszhang@kernel.org>]

Currently, cadence-xspi depends on 64BIT. This dependency isn't from
cadence xspi controller itself, but from marvell support code and 64bit
slave dma interface performance optimization.

Put marvell support code under CONFIG_64BIT to remove one reason of
the 64BIT dependency.
