mfd: sm501: Switch to BIT() to mitigate integer overflows
If offset end up being high enough, right hand expression in functions
like sm501_gpio_set() shifted left for that number of bits, may
not fit in int type.
Just in case, fix that by using BIT() both as an option safe from
overflow issues and to make this step look similar to other gpio
drivers.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
