[ Upstream commit c3aa5cb264a38ae9bbcce32abca4c155af0456df ]
AHB memory as MMIO should be mapped with ioremap rather than ioremap_wc,
which should have been used initially just to handle unaligned access as
a workaround.
Fixes: d166a73503ef ("spi: fspi: dynamically alloc AHB memory")

[ Upstream commit 2ec8b010979036c2fe79a64adb6ecc0bd11e91d1 ]
We don't want to use the value of ilog2(0) as dummy.buswidth is 0 when
dummy.nbytes is 0. Since we have no dummy bytes, we don't need to
configure the dummy byte bits per clock register value anyway.
