FDT, clk_fixed: add gated-fixed-clock support and deferred initialization

- Add CLK_TYPE_GATED_FIXED with GPIO-based gate control.
- Support optional vdd-supply regulator.
- Delay clknode registration until parent clock and other dependencies
  are present (via new_pass).

While I'm in, switch license header to the new SPDX format.

sound tests: Check the return value of close(2)

While here, remove two munmap(2) calls on mappings the tests require to
have failed, since they are practically dead.

sound: Let pcm_unregister() tear down a partially initialized device

Since 3107b952f534 ("sound: Merge PCM_ALIVE() with PCM_REGISTERED()"),
pcm_unregister() is gated on PCM_REGISTERED(), so it cannot run unless
pcm_register() has already succeeded, which means drivers will leak
resources if a failure happened prior to this.

Reintroduce PCM_ALIVE(), but test dev rather than the lock. pcm_init()
assigns dev before anything else, so it can tell us whether pcm_init()
has run or not. Make sure to clear it in pcm_unregister() so that a
second call to pcm_unregister() cannot double-free.

While here, publish to sndstat(4) only once pcm_register() has
succeeded.
