rockchip: gpio: rk_gpio: use ROCKCHIP_GPIOS_PER_BANK as divider
The current divider to calculate the bank ID can change.
Given the Rockchip TRM not all gpio-banks have 32 pins per bank.
The "gpio-ranges" syntax allows multiple items with variable number
of pins. Use a constant ROCKCHIP_GPIOS_PER_BANK as fixed divider.
