1.check the rpmsg name when clk_register.
2.clk_get rpmsg clk print error:
clk/clk.c:1231:3: runtime error: null pointer passed as argument 2, which is declared to never be null
3.fix some function miss keyword FAR.
4.clk_disable_unused may disable rpmsg clk which disable the clk that maybe used by others

1.client get the regualtor which is enabled by server, will disable the regualtor.
2.regulator_rpmsg_server_unbind will disable regualtor which maybe used by other client.
3.regulator_rpmsg_server_unbind will be deadloop when the regulator is always_on;
4.regulator_rpmsg_client_destroy does not match server cpu name,may destory by stop other rptun dev

These structures need to be aligned with the firmware, packed_struct will cause the scan information from Wi-Fi firmware not to be parsed by broadcom Wi-Fi driver. Therefore, we need to remove the packed_struct of the structure associated with the scan information.

Solve the problem that when a user modifies the sampling rate,
the difference between the generation and the mainline generation
may be greater than the own sampling interval.
After this problem occurs, sensor_is_update() will continue to
return true, resulting in a busy loop in the upper-layer application,
so, need update user generation according to mainline generation.

When the upper layer calls goldfish_camera_data_uninit, priv->capture_cb=NULL, but when there is data transmission in goldfish_camera_thread, priv->capture_cb will be called, which will cause a crash.

It uses the memory block as the serial communication medium, which can communicate between different processes or different CPUs
Using the following configuration, the cross-core communication rate of 200MHz cortex-M55 is about 461KB/s

A dead lock may happen before this patch:
rptun thread (usrsock_rpmsg_recvfrom_handler):
Gets all tx payload but waiting net_lock in psock_recvfrom
net driver thread (higher priority):
Receives a packet, holding net_lock, calling usrsock_rpmsg_send_event
But no tx buffer left, so rpmsg_send blocks, and won't release net_lock
In short:
Rptun: Hold all `tx_payload_buffer` -> want `net_lock`
Driver: Hold `net_lock` -> want `tx_payload_buffer`
This patch use net_lock to combine get_tx_payload and recvfrom together,
then:
- If it's waiting net_lock, tx payload will not be held, other threads
may get tx buffer and do their work.
- If net_lock is got, it won't be disturbed before finish receiving,
then tx payload won't have chance to be blocked before releasing.

tcp_poll_eventhandler have logic after poll_notify, if we teardown poll
inside poll callback without clearing revents, use-after-free will
