crypto: caam - do not reset pointer size from MCFGR register

Browse Source 
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].
