Bluetooth: hci_qca: Replace devm_gpiod_get() with devm_gpiod_get_optional()
This patch replaces devm_gpiod_get() with devm_gpiod_get_optional() to get
bt_en and replaces devm_clk_get() with devm_clk_get_optional() to get
susclk. It also uses NULL check to determine whether the resource is
available or not.
Fixes: 8a208b24d770 ("Bluetooth: hci_qca: Make bt_en and susclk not mandatory for QCA Rome")
