[PATCH 2/4] clk: thead: th1520-ap: Mark drivers as DM_FLAG_PRE_RELOC

[Yao Zi]

It's common that UARTs are bound and probed before U-Boot relocation,
in which case the clocks of UART and UART's pincontroller must be
registered first. Let's apply DM_FLAG_PRE_RELOC to the driver, allowing
it to bind before relocation.
