Remove global variable arm_linux_vfp_register_count in arm-linux-nat.c

This patch is to remove the global variable arm_linux_vfp_register_count
from arm-linux-nat.c.  This global variable is set when native gdb
looks for the right target description according HWCAP.  However,
'struct gdbarch_tdep' has already had a field have_vfp_registers, which
is a boolean about whether target has vfp registers or not.  This
patch converts this boolean field to a numeric counter to replace
global variable arm_linux_vfp_register_count.
