Bluetooth: hci_qca: Move boot delay to qca_send_power_pulse()

Matthias Kaehlcke · holtmann · commit ad571d725c97 · 2019-02-27T08:44:32.000+01:00
After sending a power on pulse the driver has a delay of 100ms
to allow the host controller to boot. Move the delay into
qca_send_power_pulse(), since it is directly related with the
power-on pulse.
