wwan: iosm: use a flexible array rather than allocate short objects
GCC array-bounds warns that ipc_coredump_get_list() under-allocates
the size of struct iosm_cd_table *cd_table.
This is avoidable - we just need a flexible array. Nothing calls
sizeof() on struct iosm_cd_list or anything that contains it.

Revert "net: wwan: iosm: firmware flashing and coredump collection"
The devlink parameters are not the right mechanism to pass
extra parameters to device flashing. The params added are
also undocumented.
This reverts commit 13bb8429ca98 ("net: wwan: iosm: firmware
flashing and coredump collection").

net: wwan: iosm: firmware flashing and coredump collection
This patch brings-in support for M.2 7560 Device firmware flashing &
coredump collection using devlink.
- Driver Registers with Devlink framework.
- Register devlink params callback for configuring device params
required in flashing or coredump flow.
- Implements devlink ops flash_update callback that programs modem
firmware.
- Creates region & snapshot required for device coredump log collection.
On early detection of device in boot rom stage. Driver registers with
Devlink framework and establish transport channel for PSI (Primary Signed
Image) injection. Once PSI is injected to device, the device execution
stage details are read to determine whether device is in flash or
exception mode. The collected information is reported to devlink user
space application & based on this informationi, application proceeds with
either modem firmware flashing or coredump collection.
