This patch intended to fix following cases:
- SoC-A has ARM GT, defines DT node for ARM GT and selects
ARM_GLOBAL_TIMER statically in Kconfig file. SoC-B has ARM GT and
defines DT node for ARM GT, but do not selects ARM_GLOBAL_TIMER
statically in Kconfig file. In case of multiplatform build ARM GT will
be implicitly enabled for SoC-B.
- There is no way to disable ARM GT without modifying Kconfig file,
once ARM_GLOBAL_TIMER is selected statically in Kconfig file.
Hence, fix above case by defining both HAVE_ARM_GLOBAL_TIMER and
ARM_GLOBAL_TIMER as recommended by 'Adding common features and make
the usage configurable' section in kconfig-language.txt. All places in
ARM folder where ARM_GLOBAL_TIMER was used now replaced on
HAVE_ARM_GLOBAL_TIMER.
