ASoC: adau1372: Fix error handling in adau1372_set_power()

Jihed Chaibi <jihed.chaibi.dev@gmail.com> says: adau1372_set_power() had two related error handling issues in its enable path: clk_prepare_enable() was called but its return value discarded, and adau1372_enable_pll() was a void function that silently swallowed lock failures, leaving mclk enabled and adau1372->enabled set to true despite the device being in a broken state. Patch 1 fixes the unchecked clk_prepare_enable() by making adau1372_set_power() return int and propagating the error. Patch 2 converts adau1372_enable_pll() to return int and adds a full unwind in adau1372_set_power() if PLL lock fails, reversing the regcache, GPIO power-down, and clock state.
