[PATCH 5.19 0720/1157] clk: mediatek: reset: Fix written reset bit offset

[Greg Kroah-Hartman]

From: Rex-BC Chen <rex-bc.chen@xxxxxxxxxxxx>

[ Upstream commit edabcf71d100fd433a0fc2d0c97057c446c33b2a ]

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")
