drivers/wifi/generic: Split wifi_generic_fill_ssdt into two functions

This change splits `wifi_generic_fill_ssdt()` into following two
functions:
1. `wifi_ssdt_write_device()`: This function writes the device, its
address, _UID and _DDN.

2. `wifi_ssdt_write_properties()`: This function writes the properties
for WiFi device like _PRW, regulatory domain and SAR.

This split is done so that the device write can be skipped for
CNVi devices in follow-up CLs. It will allow the SoC controller
representation for CNVi PCI device to be consistent with other
internal PCI devices in the device tree i.e. not requiring a
chip driver for the PCI device.

Because of this change, _PRW and SAR will be seen in a separate
block in SSDT disassembly, but it does not result in any functional
change.

Observed difference:
Before:
Scope (\_SB.PCI0.PBR1)
{
	Device (WF00)
	{
		Name (_UID, 0xAA6343DC)
		Name (_DDN, "WIFI Device")
		Name (_ADR, 0x0000000000000000)

		Name (_PRW, Package() { 0x08, 0x03 })
	}
}

After:
Device (\_SB.PCI0.PBR1.WF00)
{
	Name (_UID, 0xAA6343DC)
	Name (_DDN, "WIFI Device")
	Name (_ADR, 0x0000000000000000)
}

Scope (\_SB.PCI0.PBR1.WF00)
{
	Name (_PRW, Package() { 0x08, 0x03 })
}
