[PATCH 4/6] android: boot: Add set_abootimg_addr() and set_avendor_bootimg_addr()

The only way to configure the load addresses for both bootimg and
vendor_bootimg is by using the "abootimg" command.
If we want to use the C API, there is no equivalent.

Add set_abootimg_addr() and set_avendor_bootimg_addr() so that we can
specify the load address from C.

This can be useful for implementing an Android bootmethod.
