Subject: [PATCH] Bluetooth: hci: fix build when POWER_SEQUENCING=m

BT_HCIUART_QCA, which is a bool and an HCI UART component, uses now
power sequencing, so we need to be sure BT_HCIUART_QCA=y and
POWER_SEQUENCING=m cannot happen:

  /usr/bin/aarch64-linux-gnu-ld: drivers/bluetooth/hci_qca.o: in function `qca_serdev_probe':
  drivers/bluetooth/hci_qca.c:2401:(.text+0xc48): undefined reference to `devm_pwrseq_get'
  /usr/bin/aarch64-linux-gnu-ld: drivers/bluetooth/hci_qca.o: in function `qca_power_shutdown':
  drivers/bluetooth/hci_qca.c:2192:(.text+0x29e8): undefined reference to `pwrseq_power_off'
  /usr/bin/aarch64-linux-gnu-ld: drivers/bluetooth/hci_qca.o: in function `qca_power_on':
  drivers/bluetooth/hci_qca.c:1808:(.text+0x3390): undefined reference to `pwrseq_power_on'

Fixes: 4029dba6b6f1 ("Bluetooth: qca: use the power sequencer for QCA6390")
