armv8: Move secure_ram variable out of generic global data

Browse Source 
Secure_ram variable was put in generic global data. But only ARMv8
uses this variable. Move it to ARM specific data structure.

You only need to set this if address zero isn't writeable
- CONFIG_SYS_MEM_RESERVE_SECURE
Only implemented for ARMv8 for now.
If defined, the size of CONFIG_SYS_MEM_RESERVE_SECURE memory
is substracted from total RAM and won't be reported to OS.
This memory can be used as secure memory. A variable
gd->secure_ram is used to track the location. In systems
gd->arch.secure_ram is used to track the location. In systems
the RAM base is not zero, or RAM is divided into banks,
this variable needs to be recalcuated to get the address.
