thermal/drivers/sun8i: Fix some error handling paths in sun8i_ths_probe()

Should an error occur after calling sun8i_ths_resource_init() in the probe
function, some resources need to be released, as already done in the
.remove() function.

Switch to the devm_clk_get_enabled() helper and add a new devm_action to
turn sun8i_ths_resource_init() into a fully managed function.

Move the place where reset_control_deassert() is called so that the
recommended order of reset release/clock enable steps is kept.
A64 manual states that:

	3.3.6.4. Gating and reset

	Make sure that the reset signal has been released before the release of
	module clock gating;

This fixes the issue and removes some LoC at the same time.
