  target-xtensa: add 64-bit floating point registers

Xtensa ISA got specification for 64-bit floating point registers and
opcodes, see ISA, 4.3.11 "Floating point coprocessor option".

Add 64-bit FP registers.

Although 64-bit floating point is currently not supported by xtensa
translator, these registers need to be reported to gdb with proper size,
otherwise it wouldn't find other registers.

  target-xtensa: fix gdb register map construction

Due to different gdb overlay organization between windowed/call0
configurations core import script doesn't always work correctly.
Simplify the script: always copy complete gdb register map from overlay,
count registers at core registerstion time. Update existing cores.
