Subject: [PATCH v3 0/4] fix the SpacemiT P1 Kconfig and resend the K1 I2C
 ILCR patch.

Since P1 Kconfig directly selects K1_I2C, after the I2C ILCR patch was
merged, the driver would fail [1] when COMMON_CLK was not selected.

This series fixes the P1 Kconfig and resends the I2C ILCR patch(This
patch has reverted by maintainer [2]).

Now, P1 Kconfig patch has been merged[3], so I2C ILCR patch can be
merged as well.

In addition, the Kconfig for P1's two subdevices, regulator and RTC,
has been updated to use 'depends on MFD_SPACEMIT_P1' instead of 'select' and
change default value from `ARCH_SPACEMIT` to `MFD_SPACEMIT_P1`.
