[RESEND PATCH] i2c: at91: switched to resume/suspend callbacks.

[<Andrei.Stefanescu@microchip.com>]

In the previous version of the driver resume/suspend_noirq callbacks
were used. Because of this, when resuming from suspend-to-ram,
an I2C (belonging to a FLEXCOM) would resume before FLEXCOM.
The first read on the I2C bus would then result in a timeout.

This patch switches to resume/suspend callbacks which are 
called after FLEXCOM resumes. FLEXCOM, SPI and USART drivers use
resume/suspend callbacks.
