MAINTAINERS: Adjust sh4 maintainership

This patch transfers sh4 sections to Yoshinori Sato, who is
best positioned in the community to assume sh4 maintainership.
He is the maintainer of the related target rx as well, which
means that some synergy between the two targets can be expected
in future.

Further adjustments, reorganizations, and improvements of sh4
sections are left to the future maintainer to be devised and
executed, as he deems suitable.

Aurelien and Magnus are deleted as maintainers in some sections
of the MAINTAINERS file with this patch. However, they will not
be deleted from QEMU Hall of Fame, where their names will always
remained carved in stone as QEMU pioneers and granddaddies.
