arm: tcc8k: Avoid reading clock register twice
There is no reason why in case of PLL2 the configuration register should be read twice, while for PLL0/1 using the value previously read is used. Do the same for PLL2. Signed-off-by: Oskar Schirmer <oskar@linutronix.de> Cc: bigeasy@linutronix.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
