Watchdog: marvell_gti_wdt: Remove redundant dev_err_probe() for platform_get_irq()

Since commit 7723f4c5 ("driver core: platform: Add an error message
to platform_get_irq*()"), there is no need to call the dev_err_probe()
function directly to print a custom message when handling an error
from platform_get_irq() function as it is going to display an appropriate
error message in case of a failure.
