[PATCH] rtc: rtc-cadence: fix clock cleanup ordering

[Jiawen Liu]

From: jiawen <1298662399@xxxxxx>

The probe function enables the peripheral clock (pclk) before the
reference clock (ref_clk), and its error path disables ref_clk before
pclk. However, the remove function disables pclk before ref_clk, which
is the reverse order. This asymmetric teardown can leave the clock
framework in an inconsistent state and violates the expected lifecycle
balance. Fix the remove function to disable ref_clk first, then pclk,
matching the probe enable order and the error path cleanup order.
