spi: meson-spifc: fix runtime PM leak on remove

Browse Source 
pm_runtime_get_sync() increments the runtime PM usage counter even when it
returns an error. meson_spifc_remove() uses it to resume the controller
before disabling runtime PM, but never drops the usage counter again.

Balance the get with pm_runtime_put_noidle() after disabling runtime PM,
matching the teardown pattern used by other SPI controller drivers.

Found by static analysis. I do not have hardware to test this.
