clocksource/drivers/arm_arch_timer: Fix vDSO clockmode when vDSO disabled
The arm_arch_timer requires VDSO_CLOCKMODE_ARCHTIMER to be defined to
compile correctly. On ARM the vDSO can be disabled and when this is the
case the compilation ends prematurely with an error:
$ make ARCH=arm multi_v7_defconfig
$ ./scripts/config -d VDSO
$ make
drivers/clocksource/arm_arch_timer.c:73:44: error:
‘VDSO_CLOCKMODE_ARCHTIMER’ undeclared here (not in a function)
static enum vdso_clock_mode vdso_default = VDSO_CLOCKMODE_ARCHTIMER;
Make the usage of VDSO_CLOCKMODE_ARCHTIMER depend on the VDSO enablement
and initialize the vdso clockmode variable with VDSO_CLOCKMODE_NONE
otherwise.
