Log Message:
sdhc: avoid taking adaptive mutex while holding spin mutex

the clock_bus pre- and post- callbacks used in sdhc_bus_clock_ddr()
are called with a spin mutex held, and the new sdhc@acpi ends up
calling into (sleeping) ACPI code, triggering lockdebug assertion.

introduce an adaptive mutex that is held around these callbacks,
and reduce the spin mutex held time in sdhc_bus_clock_ddr().
