mmc: atmel-mci: change atmci_readl and atmci_writel macros
Change atmci_readl and atmci_writel macros: remove string concatenation. We can use these macros with registers which are not prefixed by ATMCI_. This is the case if we want to write PDC registers which are common to several devices so they are not prefixed with ATMCI_.
