The ufs_reset pin is expected to be wired to the reset pin of the
primary UFS memory but is pretty much just a general purpose output pinr
Reorder the pins and expose it as gpio 150, so that the UFS driver can

pinctrl variants that include pinctrl-paris.h (and not
pinctrl-mtk-common.h) also need to use pm_ops to setup
wake mask properly, so copy over the pm_ops from common
to paris variant.
It is not easy to merge the 2 copies (or move
mtk_eint_suspend/resume to mtk-eint.c), as we need to
dereference pctrl->eint, and struct mtk_pinctrl *pctl has a
different structure definition for v1 and v2 (which is
what paris variant uses).

Rework the BM1880 SoC pinmux handling by removing the
BM1880_PINMUX_FUNCTION_MUX define and merging it with the
BM1880_PINMUX_FUNCTION definition. Since the PWM muxing is handled by
generic pin controller in the SoC itself, there is no need to have a
dedicated code to do the muxing in PWM registers. So, lets club all
pinmux handling in the same per pin mux handling code.

GPIOs are split between several banks (A, B, ...) and each bank can have
up to 16 lines. Those GPIOs could be used as interrupt lines thanks to
exti lines. As there are only 16 exti lines, a mux is used to select which
gpio line is connected to which exti line. Mapping is done as follow:
-A0, B0, C0.. -->exti_line_0 (X0 selected by mux_0)
-A1, B1, C1.. -->exti_line_1 (X1 selected by mux_1)
...
This patch adds a protection to avoid overriding on mux_n for exti_line_n.
