Revert "tty: serial: bcm63xx: fix missing clk_put() in bcm63xx_uart"

This reverts commit 580d952e44de5509c69c8f9346180ecaa78ebeec ("tty:
serial: bcm63xx: fix missing clk_put() in bcm63xx_uart") because we
should not be doing a clk_put() if we were not successful in getting a
valid clock reference via clk_get() in the first place.
