mci: core: allocate memory used for DMA with dma_allocHEADmaster

Memory allocated by normal malloc may not fulfill the alignment
requirements for DMA.

This fixes memory corruption observed on the i.MX8MP when the
DMA-enabled eSDHC driver attempts to probe an eMMC.

This issues always existed, but only after commit 65ef5d885263
("ARM64: let 'end' point after the range in cache functions"), the whole
512 bytes were getting invalidated, which corrupted the TLSF malloc
header of the block after it.
