pre_req and post_req support

Hi!

commit 69e7d76afdb54243df957351804c0f1afca46d0f upstream.

Add pre_req and post_req support to improve performance.

Inspired by a patch in the BSP by Masaharu Hayakawa.
+/*
+ * renesas_sdhi_internal_dmac_map() will be called with two difference
"two different"?
Agreed.

+ /* This DMAC cannot handle if buffer is not 128-bytes alignment */
"aligned"?
Ditto.

Cheers,
Prabhakar

Best regards,
Pavel
