[PATCH V3 02/17] clk: mediatek: reset: Fix written reset bit offset

Original assert/deassert bit is BIT(0), but it's more resonable to modify
them to BIT(id % 32) which is based on id.
This patch will not influence any previous driver because the reset is
only used for thermal. The id (MT8183_INFRACFG_AO_THERM_SW_RST) is 0.
Fixes: 64ebb57a3df6 ("clk: reset: Modify reset-controller driver")
