i2c: hisi: Add gpio bus recovery support

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I610G3



--------------------------------------------------------------

Add generic GPIO bus recovery support for i2c-hisi driver
by registering the recovery information with core provided
i2c_generic_scl_recovery() method.

As the SCL/SDA pins are multiplexed with GPIO, we need to
switch the pins mux to GPIO before recovery and switch back
after recovery. It's implemented by the ACPI method in
the i2c_bus_recovery_info->{prepare,unprepare}_recovery()
method.
