xtensa: fix access to the last pseudo register
Currently access to the last pseudo register is aliased to a1. This is
done by little snippets in the beginning of xtensa_pseudo_register_read
and xtensa_pseudo_register_write that used to do such aliasing for FP
register since bdb4c075a29dd086f0868b394b488b1c94666be6, but then
FP_ALIAS was expanded into gdbarch_num_regs (current_gdbarch) +
gdbarch_num_pseudo_regs (current_gdbarch) (one register past the last
pseudo register) in 304fe2552d6e0821e8fdb7575f8e7ba6607a076d, which
then was changed to the last pseudo register in
94a0e877111421d300d26b858bd3a0a27078d1e8.
Drop these snippets.

* xtensa-tdep.c (xtensa_pseudo_register_read)

to a1.
