Currently mv col aux buffers are allocated as a pool. This is not
optimal because pool size equals number of buffers before stream is

invalid pointer is assigned to the decoding frame and Cedrus might

When moving the input selection to adv748x_reset() it was missed that
during probe the device is reset _before_ the initialization and parsing
of DT by the AFE subdevice. This can lead to the wrong input port (in
case it's not port 0) being selected until the device is reset for the
first time.
Fix this by restoring the call to adv748x_afe_s_input() in the AFE
initialization while also keeping it in the adv748x_reset().

It is possible that when remote processor crash, the communication
channel will be broken with garbage value in mailbox, such as
when Linux is issuing a message through mailbox, remote processor
crashes, we need free & rebuild the mailbox channels to make sure
no garbage value in mailbox channels.
So move the request/free to start/stop for managing remote procesosr in
Linux, move to attach/detach for remote processor is out of control of
Linux.
Previous, we just request mbox when attach for CM4 boot early before
Linux, but if mbox defer probe, remoteproc core will do resource cleanup
and corrupt resource table for later probe.
So move request mbox ealier and still keep mbox request when attach
for self recovery case, but keep a check when request/free mbox.

With just the forward declaration of the 'struct pt_regs' in
syscall_wrapper.h, the syscall stub functions:
__[x64|ia32]_sys_*(struct pt_regs *regs)
will have different definition of 'regs' argument in BTF data
based on which object file they are defined in.
If the syscall's object includes 'struct pt_regs' definition,
the BTF argument data will point to a 'struct pt_regs' record,
like:
[226] STRUCT 'pt_regs' size=168 vlen=21
'r15' type_id=1 bits_offset=0
'r14' type_id=1 bits_offset=64
'r13' type_id=1 bits_offset=128
...
If not, it will point to a fwd declaration record:
[15439] FWD 'pt_regs' fwd_kind=struct
and make bpf tracing program hooking on those functions unable
to access fields from 'struct pt_regs'.
Include asm/ptrace.h directly in syscall_wrapper.h to make sure all
syscalls see 'struct pt_regs' definition. This then results in BTF for
'__*_sys_*(struct pt_regs *regs)' functions to point to the actual
struct, not just the forward declaration.
