ASoC: SOF: Add some bounds checking to firmware data

Smatch complains about "head->full_size - head->header_size" can
underflow. To some extent, we're always going to have to trust the
firmware a bit. However, it's easy enough to add a check for negatives,
and let's add a upper bounds check as well.

ASoC: SOF: Introduce container struct for SOF firmware

Move the firmware related information under a new struct (sof_firmware)
and add it to the high level snd_sof_dev struct.

Convert the generic code to use this new container when working with the
basefw and for compatibility reasons set the old plat_data members used by
the platforms.

ASoC: SOF: ipc3-loader: Print out the non matching ext_man magic number

Print out the found extended manifest magic number in case it is not
matching with the expected one (0x6e614d58) in debug level.
It is fairly unlikely that the firmware does not have ext_man section and
the found value in place of the magic number can help rootcausing boot
related issues.

ASoC: SOF: ipc3: Remove the ipc3-ops.h header file

Only the main IPC ops struct should be visible outside of IPC3 code to make
sure that the code is correctly abstracted.

Instead of keeping the ipc3-ops.h with only the high level ops struct
declaration, put the ipc3_ops to sof-priv.h and move all other ops struct
declaration into ipc3-priv.h

New IPC implementation should follow this route: the main IPC ops should be
declared in sof-priv.h and no other IPC version related header be used
for generic code.

ASoC: SOF: ipc3-loader: Implement firmware parsing and loading

Add the IPC3 dependent implementation of validating the firmware image,
parsing the ext manifest and to load modules via memcpy.

The code introduced by this commit is the IPC dependent code from the
loader.c, which is going to be removed later.
