HV: make: skip duplicated PLATFORM= on command line

Browse Source 
Since .config has PLATFORM now, it is expected that the PLATFORM= command line
option is no longer necessary as long as a proper .config exists.

This patch implements this expectation. Now the platform to be selected is
determined by the following steps.

    1. If PLATFORM= is provided on the command line, the specified value is
       used.
    2. If there is no PLATFORM= on the command line and PLATFORM is defined in
       config.mk, its value is used.
    3. If neither PLATFORM= on the command line nor config.mk is available, a
       predefined default value is used.

v1 -> v2:

    * 'make oldconfig' should not pass CONFIG_xxx to the script since config.mk
      can be out-dated.
    * Change the default value of PLATFORM to SBL for backward compatibility of
      'make all'.
