mediatek: use existing I2C clock names

PCK and MCK should really be P=PMIC and M=MEM, which means that they
should effectively be CLK_PMIC and CLK_ARB.

-Subject: [PATCH] i2c: mt65xx: add additional clocks
-
-On MT7981 additional clocks are required when accessing I2C registers.
-Add MCK and PCK optional clocks to i2c-mt65xx driver so we don't have
-to always have them enabled, but really only if I2C is used.
