[PATCH] clocksource/drivers/pistachio: Correct output format of PTR_ERR()

[Vladimir Zapolskiy <vz@mleia.com>]

Use signed integer output in the pr_err() string format, here
PTR_ERR() value is negative and it should be reported in human
readable way.

I've occasionally found this issue, which most probably is copy-pasted
from/to drivers/clocksource/time-lpc32xx.c and recently fixed by commit
d662ed204357 ("clocksource/drivers/lpc32: Correct pr_err() output format").
