[PATCH 1/3] clk: keystone: Fix an error checking

[Christophe JAILLET]

clk_register_pll() can return ERR_PTR(-ENOMEM) so checking the return value
against NULL only is not correct.
In order to fix it, update clk_register_pll() to always return an error
pointer in case of error and check the return value with IS_ERR.

While at it, also fix a tab vs space in the surrounding code.
