clocksource/drivers/mips-gic-timer: Make gic_clocksource_of_init() return int

In commit:

  d8152bf85d ("clocksource/drivers/mips-gic-timer: Convert init function to return error")

several return values were added to a void function resulting in the following warnings:

 clocksource/mips-gic-timer.c: In function 'gic_clocksource_of_init':
 clocksource/mips-gic-timer.c:175:3: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c:183:4: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c:190:3: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c:195:3: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c:200:3: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c:211:2: warning: 'return' with a value, in function returning void [enabled by default]
 clocksource/mips-gic-timer.c: At top level:
 clocksource/mips-gic-timer.c:213:1: warning: comparison of distinct pointer types lacks a cast [enabled by default]
 clocksource/mips-gic-timer.c: In function 'gic_clocksource_of_init':
 clocksource/mips-gic-timer.c:183:18: warning: ignoring return value of 'PTR_ERR', declared with attribute warn_unused_result [-Wunused-result]

Given that the addition of the return values was intentional, it seems
that the conversion of the containing function from void to int was
simply overlooked.
