[PATCH] MAINTAINERS: Update SiFive driver maintainers

[Samuel Holland]

Add myself as a maintainer for the various SiFive drivers, since I have
been performing cleanup activity on these drivers and reviewing patches
to them for a while now. Remove Palmer as a maintainer, as he is focused
on overall RISC-V architecture support.

Collapse some duplicate entries into the main SiFive drivers entry:
 - Conor is already maintainer of standalone cache drivers as a whole,
   and these files are also covered by the "sifive" file name regex.
 - Paul's git tree has not been updated since 2018, and all file names
   matching the "fu540" pattern also match the "sifive" pattern.
 - Green has not been active on the LKML for a couple of years.
