clocksource/drivers/davinci: Fix memory leak in davinci_timer_register when init fails

[ Upstream commit fb73556386e074e9bee9fa2d253aeaefe4e063e0 ]

Smatch reports:
drivers/clocksource/timer-davinci.c:332 davinci_timer_register()
warn: 'base' from ioremap() not released on lines: 274.

Fix this and other potential memory leak problems
by adding a set of corresponding exit lables.
