The function "p2m_alloc_table" should be able to allocate 2nd stage
translation tables not only for the host's p2m but also for alternate
p2m's.

v2: Removed altp2m table initialization from "p2m_table_init".
v3: Removed initialization of the field d->arch.altp2m_active in
"p2m_table_init" to avoid altp2m initialization throughout different
files.
Merged the function "p2m_alloc_table" and "p2m_table_init".
