clocksource/drivers/arm_arch_timer: Fix read and iounmap of incorrect variable
Fix boot warning 'Trying to vfree() nonexistent vm area'
from arch_timer_mem_of_init().
Refactored code attempts to read and iounmap using address frame
instead of address ioremap(frame->cntbase).
Fixes: c389d701dfb70 ("clocksource: arm_arch_timer: split MMIO timer probing.")
