powerpc: Change memory_limit from phys_addr_t to unsigned long long
There are some device-tree nodes, whose values are of type phys_addr_t.
The phys_addr_t is variable sized based on the CONFIG_PHSY_T_64BIT.
Change these to a fixed unsigned long long for consistency.
This patch does the change only for memory_limit.
The following is a list of such variables which need the change:
1) kernel_end, crashk_size - in arch/powerpc/kernel/machine_kexec.c
2) (struct resource *)crashk_res.start - We could export a local static
variable from machine_kexec.c.
Changing the above values might break the kexec-tools. So, I will
fix kexec-tools first to handle the different sized values and then change
the above.
