drivers: spi: silabs: Don't fail to init if clock is on

asmellby · dkalowsk · commit 587807017834 · 2025-06-13T10:17:39.000-07:00
It is not an error if the clock source is already enabled. This
may happen if a bootloader has used the peripheral and not
de-initialized it before booting the application.
