* [dm][regulator] update regulator
Replace the regulator framework spinlock with a mutex
because regulator operations may sleep.
Move always-on policy into the regulator core,
keep an initial enable reference for always-on supplies,
prevent the last disable from turning them off,
and let fixed/GPIO providers report and control their actual hardware state.

1. Fixup the cooling control flow.
2. Replace the spinlock to mutex.
3. Fixup the PWM args for PWM-FAN.
4. Add GPIO-FAN

rt_data_queue_pop() holds the data queue spinlock while updating the ring
state, then calls rt_data_queue_len(). The length function tries to acquire
the same non-recursive spinlock again, causing an SMP deadlock when a pop
leaves the queue non-empty.
Add a private _data_queue_len_nolock() helper for callers which already hold
the queue lock. Keep the public rt_data_queue_len() protected by one spinlock
acquisition.
This does not change the public API, ABI, queue state transitions, low-water
mark wakeups, or event callback behavior.
Tested on a four-core Spacemit K1 with cyclic HDMI playback and by building the
SMP QEMU Virt64 RISC-V BSP with generic audio, Intel HDA and VirtIO Sound.

Add rt_bus_probe_device() to retry driver matching for a registered
but unbound device. Use it when an OFW-created platform device
is requested again, while preserving native-bus ownership
for I2C, SPI, and other non-platform devices.
Also instantiate eligible child platform devices after a parent node is registered.

Python warns about invalid escape sequences in the heap update regex patterns. Mark the patterns as raw strings so the regex values stay unchanged without relying on invalid Python escapes.

sys_select() passed the raw user-space timeout pointer straight
through to select(), unlike readfds/writefds/exceptfds which are
all validated with lwp_user_accessable() and copied into kernel
memory first. A malicious or buggy user thread could pass a
timeout pointing at unmapped or otherwise invalid memory, which
select() would then dereference directly (timeout->tv_sec /
timeout->tv_usec) without any check, from kernel context.
Validate and copy it into a kernel-local struct timeval the same
way the fd_set arguments already are, before it reaches select().

Reject IPv4 addresses outside 224.0.0.0/4 before updating the multicast MAC hash. The previous condition used AND, so it could never reject a non-multicast first octet.
