asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

Since commit 106d67398233 ("platform/chrome: cros_ec_proto: Upgrade
get_next_event to v3"), (struct cros_ec_device *)->event_data becomes
struct ec_response_get_next_event_v3.
Update the Kunit test for fixing the following error:
> Expected mock->msg.insize == sizeof(union ec_response_get_next_data_v1), but
> mock->msg.insize == 18 (0x12)
> sizeof(union ec_response_get_next_data_v1) == 16 (0x10)

Use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warning:

They tend to exceed the stack frame size limit in some specific
environment which results in the following compilation error:

cros_ec_query_all() uses cros_ec_get_host_command_version_mask() to
query the supported MKBP version; cros_ec_get_host_command_version_mask()
uses send_command() for transferring the host command.
Returning >=0 from send_command() only denotes the transfer was success.
cros_ec_get_host_command_version_mask() should check if EC wasn't happy
by checking `msg->result`.
Add a Kunit test for returning error in `msg->result` in
cros_ec_get_host_command_version_mask(). For the case,
cros_ec_query_all() should find the EC device doesn't support MKBP.
