[PATCH 5/8] firmware: cs_dsp: mock_bin: Add function to create long-offset patches

[Richard Fitzgerald <rf@opensource.cirrus.com>]

Add cs_dsp_mock_bin_add_patch_off32(). This is the same as
cs_dsp_mock_bin_add_patch() except that it puts the offset in the
new 32-bit offset field and modifies the block type to indicate
that it uses the long offset.
