MAINTAINERS: Add Andrew as M: to ARM/NUVOTON NPCM ARCHITECTURE

Nuvoton's NPCM SoCs are part of their iBMC product line[1]. NPCM arch
patches have historically gone through Joel's tree along with ASPEED
changes due to their relevance to OpenBMC. Commit df5e674
("MAINTAINERS: Switch ASPEED tree to shared BMC repository") does what
it says on the tin - we now have bmc/linux.git on git.kernel.org, and
I've picked up the maintainer role for it.

Document that I'm continuing to apply NPCM arch patches from the
openbmc@ list to the BMC tree for PRs to the SoC tree.
