gdb/xtensa: make a0-a15 pseudo registers in case of Window ABI

Browse Source 
xtensa_pseudo_register_read/write implement access to a0-a15 registers
in the case of Window ABI. However the split between 'raw' and
'pseudo' registers was made based on the location of the first masked
register. To make access to a0-a15 go through the pseudo register
mechanism, the split should be set based on the location of a0,
instead.
