Subject: [PATCH] at91: at91sam9g20ek modify dual slot evaluation kit
at91sam9g20ek rev. C and onwards embed two SD/MMC slots. This patch modify the
previous dual slot board definition to match the official rev. C board. It also
allows the use of at91_mci SD/MMC driver in addition to the atmel-mci one.
Some pins have been re-affected from leds or Ethernet phy IRQ to the SD/MMC
slot A. This lead to a modification of those definitions.

This is a modification of the changes introduced by the patch:
"AT91: atmel-mci: Platform configuration to the the atmel-mci driver" that went
into mainline through the MMC path (thanks to Andrew Morton).
Also move slightly the 2MMC board Kconfig entry.
