lmb: use a different bit position for LMB_NOMAP
The LMB memory region attributes flags are used to specify the
behaviour of the memory regions with respect to allocations -- for
e.g. it is allowed to re-allocate a memory region already reserved
with the LMB_NONE flag. The flags use values with different bit
positions through the BIT() macro. Move the LMB_NOMAP value to bit
position 1, and also move the other flags accordingly. Using bit
position 0 for LMB_NOMAP results in the logic in
lmb_print_region_flags() to break, which prints an incorrect value for
the regions with LMB_NOMAP atribute.
