i2c: designware-pci: use IRQF_COND_SUSPEND flag
This is effectively reapplies the commit b0898fdaffb2 ("i2c: designware-pci: use
IRQF_COND_SUSPEND flag") after the commit d80d134182ba ("i2c: designware: Move
common probe code into i2c_dw_probe()"). Original message as follows.
The mentioned flag fixes a warning on Intel Edison board since one of the I2C
controller shares IRQ line with watchdog timer.
