Taras Kondratiuk fafd391234 i2c: omap: Clear ARDY bit twice ...

commit 4cdbf7d346 upstream.

Initially commit cb527ede1b
"i2c-omap: Double clear of ARDY status in IRQ handler"
added a workaround for undocumented errata ProDB0017052.
But then commit 1d7afc9594
"i2c: omap: ack IRQ in parts" refactored code and missed
one of ARDY clearings. So current code violates errata.
It causes often i2c bus timeouts on my Pandaboard.

This patch adds a second clearing in place.
