arm64/cpufeature: Store elf_hwcaps as a bitmap rather than unsigned long
When we added support for AT_HWCAP2 we took advantage of the fact that we
have limited hwcaps to the low 32 bits and stored it along with AT_HWCAP
in a single unsigned integer. Thanks to the ever expanding capabilities of
the architecture we have now allocated all 64 of the bits in an unsigned
long so in preparation for adding more hwcaps convert elf_hwcap to be a
bitmap instead, with 64 bits allocated to each AT_HWCAP.
There should be no functional change from this patch.
