gpio: aggregator: Wrap access to gpiochip_fwd.tmp[]
The tmp[] member of the gpiochip_fwd structure is used to store both the
temporary values bitmap and the desc pointers for operations on multiple
GPIOs. As both are arrays with sizes unknown at compile-time, accessing
them requires offset calculations, which are currently duplicated in
gpio_fwd_get_multiple() and gpio_fwd_set_multiple().
Introduce (a) accessors for both arrays and (b) a macro to calculate the
needed storage size. This confines the layout of the tmp[] member into
a single spot, to ease maintenance.
