[RFC PATCH v6 19/43] arm/p2m: Change function prototype of p2m_alloc_table

[Rose.Spangler@xxxxxxxxxxxxxx]

From: Sergej Proskurin <proskurin@xxxxxxxxxxxxx>

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.

This commit is a refactor and contains no functional changes.

This is commit 8/12 of the altp2m_init/altp2m_teardown routines phase.

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".
