pinctrl: rockchip: better show irq chip name

Browse Source 
When call irq_alloc_domain_generic_chips, pass the name of the irq
chip with bank name instead of just rockchip_gpio_irq.
So we can know the irq belong to which gpio by read /proc/interrupts.

cat /proc/interrupts

before:
 56:        435  rockchip_gpio_irq   3 Level     bcmsdh_sdmmc
 58:          0  rockchip_gpio_irq   5 Edge      power
 87:          2  rockchip_gpio_irq   2 Level     fusb302
105:         36  rockchip_gpio_irq  20 Level     gt9xx
106:          0  rockchip_gpio_irq  21 Level     rk808
109:          0  rockchip_gpio_irq  24 Level     fusb302
209:         42  rockchip_gpio_irq  28 Edge      es8316_interrupt

after:
 56:        401     gpio0   3 Level     bcmsdh_sdmmc
 58:          0     gpio0   5 Edge      power
 87:          2     gpio1   2 Level     fusb302
105:         39     gpio1  20 Level     gt9xx
106:          0     gpio1  21 Level     rk808
109:          0     gpio1  24 Level     fusb302
209:         37     gpio4  28 Edge      es8316_interrupt
