Subject: [PATCH] Fix compile error for MMC_AT91

Hi Andrew,

latest git doesn't compile for me with CONFIG_MMC_AT91 enabled:

/home/jan/work/linutronix/linux-2.6/drivers/mmc/host/at91_mci.c: In function `at91_mci_enable':
/home/jan/work/linutronix/linux-2.6/drivers/mmc/host/at91_mci.c:375: error: `AT91_MCI_RDPROOF' undeclared (first use in this function)
/home/jan/work/linutronix/linux-2.6/drivers/mmc/host/at91_mci.c:375: error: (Each undeclared identifier is reported only once
/home/jan/work/linutronix/linux-2.6/drivers/mmc/host/at91_mci.c:375: error: for each function it appears in.)
/home/jan/work/linutronix/linux-2.6/drivers/mmc/host/at91_mci.c:375: error: `AT91_MCI_WRPROOF' undeclared (first use in this function)
make[4]: *** [drivers/mmc/host/at91_mci.o] Error 1

This patch introduces the necessary defines (which are already present
in your tree).
