Arunpravin Paneer Selvam 0a1844bf0b drm/buddy: Improve contiguous memory allocation
Problem statement: The current method roundup_power_of_two()
to allocate contiguous address triggers -ENOSPC in some cases
even though we have enough free spaces and so to help with
that we introduce a try harder mechanism.

In case of -ENOSPC, the new try harder mechanism rounddown the
original size to power of 2 and iterating over the round down
sized freelist blocks to allocate the required size traversing
RHS and LHS.

As part of the above new method implementation we moved
contiguous/alignment size computation part and trim function
to the drm buddy file.

v2: Modify the alloc_range() function to return total allocated size
    on -ENOSPC err and traverse RHS/LHS to allocate the required
    size (Matthew).
