[PATCH] gpio: gpio-exar: replace division condition with direct comparison

[Suraj Sonawane <surajsonawane0215@xxxxxxxxx>]

Fix an issue detected by the Smatch tool:

drivers/gpio/gpio-exar.c:52 exar_offset_to_sel_addr() warn:
replace divide condition 'pin / 8' with 'pin >= 8'
drivers/gpio/gpio-exar.c:62 exar_offset_to_lvl_addr() warn:
replace divide condition 'pin / 8' with 'pin >= 8'

The division 'pin / 8' was used to check if the pin number is 8 or greater,
which can be confusing and less readable. Replacing it with 'pin >= 8'
makes the code clearer by directly comparing the pin number. This also
removes reliance on integer division, which can be harder to understand
and may introduce subtle bugs in the future.
