ACP7.B and ACP7.F require signed firmware to be authenticated by the
AMD Security Processor (ASP) before the DSP can execute it. Implement
a new two-stage firmware load path via the ASP MPASP mailbox.
Stage 1 (probe time): query ASP for the physical base address and ATU
group assignment of a pre-allocated 32 MB MALL carveout region. If
ASP does not support carveout, probe fails immediately.
Stage 2 (load time): load the signed image from disk, send it to ASP
via VALIDATE_IMAGE; ASP authenticates the image and deposits the raw
binary into the carveout. The driver then SHA-DMAs the raw binary from
the carveout into DSP IRAM.
On D3->D0 resume the raw binary is preserved in the carveout; the
driver skips the filesystem load and ASP authentication and restores
directly from the saved carveout address.

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Newer AMD SOC differs slightly in terms of few registers offset and
configuration. Add offsets into chip_info struct to make core ACP
code more generic and resusable on newer SOC.

ACP_SRAM_PTE block has cache that needs to be flushed after every
PTE updates. This patch updates ACPAXI2AXI_ATU_CTRL register to
flush cache after updating PTE with stream physical address.
