[ARM] 4151/1: AT91 / AVR32: Move at91_pdc.h to linux/atmel_pdc.h
The Atmel AT91 and AVR32 processor architectures share many of the same peripherals. The PDC (Peripheral Data Controller) registers are also implemented within in a number of the on-chip peripherals (eg, USART, MMC, SPI, SSC, etc). In a attempt not to duplicate the register definitions in each peripheral, or in each architecture, the at91_pdc.h header in asm-arm/arch-at91 and asm-avr32/arch-at32ap has been replaced with linux/atmel_pdc.h. The definitions have also been renamed from AT91_PDC_* to ATMEL_PDC_*, and the drivers updated accordingly. Original patch from Nicolas Ferre.
