* cdl/hal_arm_at91sam7s.cdl: Implement the SPI bus 1 interface for
the SAM7X and SAM7XC.
* include/plf_io.h: Add SPI DMA registers.
include/pkgconf/mlt_arm_at91sam7x128_rom.{h|ldi}
include/pkgconf/mlt_arm_at91sam7x256_rom.{h|ldi}: Linker files
for AT91SAM7X processor.
* src/at91sam7s_misc.c: Use the AT91 generic PIO manipulation
macros. Move the LED function out into the board specific HAL
package.
