David Karoly adc32659fb arm: enable enforcing memory access permissions 
Bootloader:
* set permissions to kernel read/write, no user access
  for initially mapped memory areas
* set permissions to kernel read/write, no execute,
  no user access for UART

Kernel:
* physical memory mapper uses kernel read/write mapping
  with no-execute bit enabled
* all other pages are mapped as read/write/execute for
  kernel and user
* proper access permissions and memory types to be
  implemented later

Enforce memory access permissions by setting DACR to
client mode for domain #0, no access for other domains.

see ARM Architecture Reference Manual, section B3.7 Memory access control
and in particular the following subsections:
B3.7.1 Access permissions
B3.7.2 Execute-never restrictions on instruction fetching
B3.7.3 Domains, Short-descriptor format only
