[PATCH] ARM: dts: stm32mp13: Add support of ck_usbo_48m in pre-reloc stage

[Patrice Chotard]

From: Patrick Delaunay <patrick.delaunay at foss.st.com>

The clock ck_usbo_48m is a clock source for RCC, so the ck_usbo_48m
clock provided by usbphyc need to be probed when RCC clock driver is
required, in pre-reloc stage.

This patch allow to remove the following warning:

clk_register: failed to get ck_usbo_48m device (parent of usbo_k)
