hikey960: Remove hifi dsp support.

The hifi dsp support wasn't frequently used nor enabled by
default. Since we are moving binary firmware objects to the
vendor package, just remove the hifi dsp logic and firmware
all together.

This patch reapplies the reverted patch of the same name,
as issues were seen when the vendor package was missing.

- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.

- *	h           (short)			expands to int on 32-bit Xtensa
- *	l           (long)			same as int on 32-bit Xtensa
