clk: mediatek: use en_mask as a pure div_en_mask
We no longer allow en_mask to be a combination of
pll_en_bit and div_en_mask, so remove pll_en_bit(bit0)
from en_mask to make en_mask a pure en_mask that only
used for pll dividers.
This commit continues the work done in commit 7cc4e1bbe300
("clk: mediatek: Fix asymmetrical PLL enable and disable
control") and commit f384c44754b7 ("clk: mediatek:
Add configurable enable control to mtk_pll_data") to
clean up en_mask(bit0) default setting.
