[PATCH 2/9] arm64: Fix INVALID_HWID definition

Change the preprocessor macro INVALID_HWID definition from ULONG_MAX to (~0)
to allow INVALID_HWID to be used within assembly source files.

Commit 3e98fdacc59bbbdbb659be1a144ccc48ed4860fa (arm64: kernel: make the pen of
the secondary a 64-bit unsigned value) added the preprocessor macro INVALID_HWID
to asm/cputype.h with it defined to be ULONG_MAX.  Use of INVALID_HWID in an
assembly source file that includes cputype.h will generate an assembler
undefined symbol ULONG_MAX build error.  The kernel does define a ULONG_MAX in
kernel.h, but that file not setup to be included in assembly files.
