arm64: errata: Add -mpc-relative-literal-loads to build flags
GCC6 (and Linaro's 2015.12 snapshot of GCC5) has a new default that uses
adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419
is enabled, modules built with this toolchain fail to load:
module libahci: unsupported RELA relocation: 275
This patch fixes the problem by passing '-mpc-relative-literal-loads'
to the compiler.
