Alan Hayward 0f83012ea0 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):

	Likewise.
	(aarch64_linux_get_hwcap): Remove function.
	* aarch64-linux-tdep.h (aarch64_linux_get_hwcap): Remove
	declaration.
