MAINTAINERS: Update bouncing @codeaurora addresses for EMMC CMDQ

The @codeaurora email domain's servers have been decommissioned for a
long while now, and any emails addressed there will bounce.

Asutosh has an entry in .mailmap pointing to a new address, but
MAINTAINERS still lists an old @codeaurora address. Update MAINTAINERS
to match .mailmap for anyone reading the file directly.

Ritesh appears to have changed jobs, but looks to be still active in the
community. Update Ritesh's address to the one used in recient community
postings. Also Ritesh has indicated their entry should be changed from
Maintainer (M:) to Reviewer (R:) so make that update while we are making
changes to the entry.
