In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also during re-reloc state") the earlier guard against setting clock defaults in pre-reloc state was removed. While it is easy to filter 'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS, no such mechanism exists for the pre-reloc stage of the full U-Boot.
With the default defconfig for the RK3399-Q7 (which filter the 'assigned-clocks' property for the DTS used by SPL anyway), this caused a pause during startup of the full U-Boot stage that lasted for almost 10s (due to the CPU not having been clocked up yet).
This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow clock defaults to be set also during re-reloc state") and extends it to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will now run in pre-reloc state for SPL, but only after reloc for the full U-Boot.

Applied to u-boot/master, thanks!
