Subject: [v7,0/2] introduce TI reset controller for MT8192 SoC 

v7:
1. [v7,1/2] remove "mediatek,reset-bit" property from mediatek-syscon-reset.yaml in [v6,1/3]
2. [v7,2/2] use the flag "MTK_SYSCON_RESET_FLAG" to determine whether to call "mtk_syscon_reset",
which integrate assert and deassert together.
3. The patch "[v6,3/3] reset-controller:ti:force the write operation when assert or deassert" has been applied

v6:
fix the format error of mediatek-syscon-reset.yaml

v5:
1. revert ti-syscon-reset.txt, and add a new mediatek reset binding.
2. split the patch [v4, 3/4] with the change to force write and the
change to integrate assert and deassert together.
3. separate the dts patch from this patch sets

v4:
fix typos on v3 commit message.

v3:
1. revert v2 changes.
2. add 'reset-duration-us' property to declare a minimum delay,
which needs to be waited between assert and deassert.
3. add 'mediatek,infra-reset' to compatible.

v2 changes:
https://patchwork.kernel.org/patch/11697371/
1. add 'assert-deassert-together' property to introduce a new reset handler,
which allows device to do serialized assert and deassert operations in a single
step by 'reset' method.
2. add 'update-force' property to introduce force-update method, which forces
the write operation in case the read already happens to return the correct value.
3. add 'generic-reset' to compatible

v1 changes:
https://patchwork.kernel.org/patch/11690523/
https://patchwork.kernel.org/patch/11690527/
