This allows rtc_gpio_deinit to always switch the pad back to GPIO,
regardless of lp io clock enabled or not, so that gpio_config can
always switch the IO back to GPIO use after wakeup from deep sleep.
Introduced in 8818157e42
The workaround in the commit routes the signal to LP GPIO matrix first.
When uses LP IOMUX pin as UART RX, the signal did not bypass the matrix,
which caused the issue.
This commit adds rtc_gpio_iomux_input and rtc_gpio_iomux_output APIs
to align with existing GPIO driver APIs.
