device: Move resource allocation into a separate compilation unit
This change moves the resource allocator functions out of device.c
and into two separate files:
1. resource_allocator_v3.c: This is the old implementation of
resource allocator that uses a single window for resource
allocation. It is required to support some AMD chipsets that do not
provide an accurate map of allocated resources by the time the
allocator runs. They work fine with the old allocator since it
restricts itself to allocations in a single window at the top of the
4G space.
2. resource_allocator_common.c: This file contains the functions that can
be shared by the old and new resource allocator.
Entry point into the resource allocation is allocate_resources() which
can be implemented by both old and new allocators. This change also
adds a Kconfig option RESOURCE_ALLOCATOR_V3 which enables the old
resource allocator. This config option is enabled by default
currently, but in the following CLs this will be enabled only for the
broken boards.
Reason for this split: Both the old and new resource allocators need
to be retained in the tree until the broken chipsets are fixed.
