Add linux_get_hwcap
Tidy up calls to read HWCAP (and HWCAP2) by adding common functions,
removing the PPC and AArch64 specific versions.
The only function difference is in aarch64_linux_core_read_description - if
the hwcap read fails it now return a valid description instead of nullptr.
gdb/ChangeLog:
2019-03-25 Alan Hayward <alan.hayward@arm.com>
* aarch64-linux-nat.c (aarch64_linux_nat_target::read_description):
Call linux_get_hwcap.
