[PATCH] clocksource/mips-gic-timer: Fix an error code in 'gic_clocksource_of_init()'

[Christophe JAILLET]

'clk' is a valid pointer at this point. So calling PTR_ERR on it is
pointess.
Return the error code from 'clk_prepare_enable()' if it fails instead.

Not compile tested as I don't have the corresponding cross-compiler
