The drivers will support OFW and name probe both.
We should make build OK when OFW is disable.

Improved README document
- Unified the usage process of Standard Edition and Smart Edition.
- Deleted the description of running RTT in Machine Mode. Currently,
both Standard Edition and Smart Edition RTT run in S-mode by default.
At the same time, some unnecessary scripts were cleaned up.

POSIX.1 says:
> read() attempts to read up to count bytes from file descriptor fd
> into the buffer starting at buf.
On the other hand, for rt_device_read, the `@size` is defined as the
number of unit (block size for blk device, otherwise one byte).
Changes:
- Transferred unit size from POSIX R/W(in bytes) to rt_device_R/W during
request of file R/W operations.

This patch introduces `rt_smp_call_request` API to handle queued
requests across cores with user provided data buffer, which provides a
way to request IPI through a non-blocking pattern.
It also resolved several issues in the old implementation:
- Multiple requests from different cores can not be queued in the work
object of the target core.
- Data racing on `rt_smp_work` of same core. If multiple requests came
in turns, or if the call is used by the target cpu, while a new
request is coming, the value will be overwrite.
- Memory vulnerability. The rt_smp_event is allocated on stack, though
the caller may not wait until the call is done.
- API naming problem. Actually we don't provide a way to issue an IPI to
ANY core in mask. What the API do is aligned to MANY pattern.
- FUNC_IPI registering to PIC.
Changes:
- Declared and configured the new `RT_SMP_CALL_IPI` to support
functional IPIs for task requests across cores.
- Replaced the single `rt_smp_work` array with `call_req_cores` to
manage per-core call requests safely.
- Added `_call_req_take` and `_call_req_release` functions for atomic
handling of request lifetimes, preventing data race conditions.
- Replaced single event handling with a queue-based approach
(`call_queue`) for efficient multi-request processing per core.
- Introduced `rt_smp_call_ipi_handler` to process queued requests,
reducing IPI contention by only sending new requests when needed.
- Implemented `_smp_call_remote_request` to handle remote requests
with specific flags, enabling more flexible core-to-core task
signaling.
- Refined `rt_smp_call_req_init` to initialize and track requests
with atomic usage flags, mitigating potential memory vulnerabilities.
