rGc2a55efd74cc: jme: Convert driver to CTLFLAG_MPSAFE

Summary

Replace CTLFLAG_NEEDGIANT with CTLFLAG_MPSAFE for all interrupt
coalescing sysctls. The driver uses jme_mtx mutex for proper
synchronization and does not require Giant lock.

Sysctls converted:

dev.jme.X.tx_coal_to (TX coalescing timeout)
dev.jme.X.tx_coal_pkt (TX coalescing packet count)
dev.jme.X.rx_coal_to (RX coalescing timeout)
dev.jme.X.rx_coal_pkt (RX coalescing packet count)
dev.jme.X.process_limit (max RX events to process)

speaker, clock: Replace Giant lock with fine-grained locking

Add sx lock to the speaker driver to protect spkr_active and spkr_inbuf,
removing the D_NEEDGIANT flag. Add mtx_lock_spin protection for timer2_state
in clock.c timer_spkr_acquire/release functions.
