ARM cache handling fixes

• boot: Use the normal outer and inner WBWA attribute also for ARMv6
• kernel: Fix comment in page_armv6.h:set_pt_level0_flags(). TEX=5, C=0, B=1 encodes outer and inner WBWA normal memory.
• Treat all normal memory as non shareable also on ARMv6.
• Make sure D$ is invalidated in cpu_arch_init() before it is enabled.
• For non-cacheable ARMv6+ memory, use device memory type instead of strongly-ordered.
• For ARMv5-, use either cached/buffered (CB=0b11) or uncached/unbuffered (CB=0b00).
