Replace regcache_raw_read with regcache->raw_read

The patch later in this series will move regcache's raw_read and
cooked_read methods to a new class regcache_read, and regcache is
dervied from it.  Also pass regcache_read instead of regcache to gdbarch
methods pseudo_register_read and pseudo_register_read_value.  In order
to prepare for this change, this patch changes regcache_raw_read to
regcache->raw_read.  On the other hand, since we are in C++, I prefer
using class method (regcache->raw_read).
