Revert "soc: intel_adsp: fix linker script for cavs_v20"

This reverts commit 3cc14b2c2b12abfd3c18c5245eaca0fbd5b21b49.

Revert this due to the same reason as commit
a29b66bbf5fbe6a77b9055ce6a7cf260e2d0dd0a:

  Unfortunately this mechanism doesn't seem to actually work on the SDK
  linker.  The emitted sections, when passed a symbol name as the "start
  address" just appear wherever the "." variable was pointing (in this
  case, into the cached region).  That breaks the kernel coherence
  layer, obviously.

#define LP_SRAM_REGION lpram

/* DSP RAM regions (all of them) are mapped twice on the DSP: once in
 * a 512MB region from 0x80000000-0x9fffffff and again from
 * 0xa0000000-0xbfffffff.  The first mapping is set up to bypass the
 * L1 cache, so it must be used when multiprocessor coherence is
 * desired, where the latter mapping is best used for processor-local
 * data (e.g. stacks) or shared data that is managed with explicit
 * cache flush/invalidate operations.
 *
 * These macros will set up a segment start address correctly,
 * including alignment to a cache line.  Be sure to also emit the
 * section to ">ram :ram_phdr" or ">ucram :ucram_phdr" as
 * appropriate. (Forgetting the correct PHDR will actually work, as
 * the output tooling ignores it, but it will cause the linker to emit
 * 512MB of unused data into the output file!)

/* DSP RAM regions (all of them) are mapped twice on the DSP: once in
 * a 512MB region from 0x80000000-0x9fffffff and again from
 * 0xa0000000-0xbfffffff.  The first mapping is set up to bypass the
 * L1 cache, so it must be used when multiprocessor coherence is
 * desired, where the latter mapping is best used for processor-local
 * data (e.g. stacks) or shared data that is managed with explicit
 * cache flush/invalidate operations.
 *
 * The UNCACHED_RAM_OFFSET will be used before to move the address
 * pointer forward or backward so code and data land in correct
 * region. Remember to align the memory, and be sure to also emit the
 * section to ">ram :ram_phdr" or ">ucram :ucram_phdr" as
 * appropriate. (Forgetting the correct PHDR will actually work, as
 * the output tooling ignores it, but it will cause the linker to emit
 * 512MB of unused data into the output file!)
