Add VCORE_FREE_{PA,SZ,END_PA} defines to identify the unused and free
memory range at the end of TEE_RAM_START..(TEE_RAM_START +
TEE_RAM_VA_SIZE).
VCORE_FREE_SZ is 0 in a pager configuration since all the memory is
used by the pager.
The VCORE_FREE range is excluded from the TEE_RAM_RW area for
CFG_NS_VIRTUALIZATION=y and instead put in a separate NEX_RAM_RW area.
This makes each partition use a bit less memory and leaves the
VCORE_FREE range available for the Nexus.
The VCORE_FREE range is added to the TEE_RAM_RW area for the normal
configuration with CFG_NS_VIRTUALIZATION=n and CFG_WITH_PAGER=n. It's in
practice unchanged behaviour in this configuration.
