[PATCH v4 0/4] Fix SSR(SubSystem Restart) issues caused by BT_EN being pulled up by hardware

[Shuai Zhang]

This patch series addresses issues encountered during SSR when
the BT_EN pin is pulled up by hardware. The main issues fixed are:

1. Timeout when sending reset command.
2. IBS state of host and controller not being synchronized.
3. Multiple triggers of SSR generating only one coredump file.
4. SSR process failed due to tx_idle_timer timeout
