[PATCH] rtc: lpc24xx: fix clock disable order in remove

From: jiawen <[email protected]>

lpc24xx_rtc_probe enables clk_rtc before clk_reg, and its error path
disables clk_reg before clk_rtc. However, lpc24xx_rtc_remove disables
clk_rtc before clk_reg, which is the opposite order. This can leave a
clock prepared if probe fails after enabling both clocks, since remove
is not called on the error path.

Fix the remove function to disable clk_reg before clk_rtc, matching the
enable order and the error path cleanup order.
