clk: clk-xgene: simplify if-if to if-else

Replace `if (!pclk->param.csr_reg)` with `else` for simplification
and add curly brackets according to the kernel coding style:

"Do not unnecessarily use braces where a single statement will do."

...

"This does not apply if only one branch of a conditional statement is
a single statement; in the latter case use braces in both branches"
