memblock: drop memblock_free_early_nid() and memblock_free_early()

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2071840
Tested: This is one of a series of patch sets to enable Arm SystemReady IR
 support in the kernel for NXP i.MX8 platforms.  At this stage, this
 has been tested by ensuring we can survive the CI/CD loop -- i.e.,
 that we have not broken anything else, and a simple boot test.  When
 sufficient drivers have been brought in for i.MX8M, we will be able
 to run further tests.

    memblock: drop memblock_free_early_nid() and memblock_free_early()

    memblock_free_early_nid() is unused and memblock_free_early() is an
    alias for memblock_free().

    Replace calls to memblock_free_early() with calls to memblock_free() and
    remove memblock_free_early() and memblock_free_early_nid().
