Since no single Mediatek chip use code for PINCTRL_MTK and code for
PINCTRL_MTK_MOORE/PINCTRL_MTK_PARIS simultaneously, it is better to use
different config to determine if related code will be built or not on
building non-generic kernel.
Add kernel config PINCTRL_MTK_V2 selected by either PINCTRL_MTK_MOORE
or PINCTRL_MTK_PARIS.
Use PINCTRL_MTK and PINCTRL_MTK_V2 to control building of
drivers/pinctrl/medaitek/.
Remove selection of EINT_MTK from PINCTRL_MTK since code for EINT_MTK is
only related to PINCTRL_MTK_MOORE/PINCTRL_MTK_PARIS, i.e. PINCTL_MTK_V2.

PINCTRL_MTK also depends on EINT_MTK such as the symbol
mtk_eint_do_init, it is a common library for the two kinds of the
pinctrl core.

I would think it is good if deciding V1 or not should be done inside
the vendor directory and the change also would cause COMPILE_TEST not
be applied to

Dear reviewer,
The points of Sean are right. Please forget this patch proposal.

Yes, you are right.
It is my fault that I don't see some mtk_eint_* functions originally in
pinctrl-mtk-common.c had been moved to mtk-eint.c since kernel-4.18 and
now pinctrl-mtk-common.c depends on mtk-eint.c.
