ata: sata_gemini: unwind clocks on IDE pinctrl errors

gemini_sata_bridge_init() prepares and enables both SATA PCLKs, then
disables them again while keeping the clocks prepared for later bridge
start and stop operations. If gemini_setup_ide_pins() fails after that,
gemini_sata_probe() returns directly and skips the existing
out_unprep_clk unwind path.

Route the IDE pinctrl failure through out_unprep_clk so the clocks
prepared by gemini_sata_bridge_init() are unprepared before probe
fails.
