commit 7278fa25aa0ebcc0e62c39b12071069df13f7e77 upstream.
In commit 'a1cf573ee95 ("crypto: caam - select DMA address size at runtime")'
CAAM pointer size (caam_ptr_size) is changed from
sizeof(dma_addr_t) to runtime value computed from MCFGR register.
Therefore, do not reset MCFGR[PS].
Fixes: a1cf573ee95 ("crypto: caam - select DMA address size at runtime")
