Changes in v3: add comment from Bo shen
- fix AT91_PMC_MCKR_CSS_MASK and AT91_PMC_MCKR_PRES_MASK
- make matrix_init weak, and add it in the taurus board code
- do not introduce ifdef mess for the differences between the SoCs,
instead use a seperate file for each SoC:
- for armv5 (arm926ejs, now at91 series), named it spl_at91.c,
- for armv7 (cortex-a5, now, sama5d3), named it spl_atmel.c
- move common code to arch/arm/cpu/at91-common/spl.c
Changes in v2: None
