NCI provides possible way to run loopback testing has done over HCI.

For us it offers many advantages:
- It simplifies the code: No more need for a vendor_cmds structure
- Loopback over HCI may not be supported in future st-nci firmware

When st_nci_spi_acpi_request_resources() gets called we
already know that the entries in -&gt;acpi_match_table have
matched ACPI ID of the device.
In addition spi_device pointer cannot be NULL in any case
(otherwise SPI core would not call -&gt;probe() for the driver
in the first place).

Drop the two useless checks from the driver.

commit 10cf4899f8af ("gpiolib: tighten up ACPI legacy gpio lookups")

If _DSD properties are available in an ACPI node, we are not
allowed to fallback to _CRS data to retrieve gpio properties.
This was causing us to fail if uicc-present and/or ese-present
are defined.

To be consistent with devicetree change ST_NCI_GPIO_NAME_RESET
content to reset so that acpi_find_gpio in drivers/gpio/gpiolib.c
will look for reset-gpios. In the mean time the ACPI table needs
to be fixed as follow (Tested on Minnowboard Max):

Since
commit 10cf4899f8af ("gpiolib: tighten up ACPI legacy gpio lookups")

If _DSD properties are available in an ACPI node, we are not
allowed to fallback to _CRS data to retrieve gpio properties.
This was causing us to fail if uicc-present and/or ese-present
are defined.

To be consistent with devicetree change ST_NCI_GPIO_NAME_RESET
content to reset so that acpi_find_gpio in drivers/gpio/gpiolib.c
will look for reset-gpios. In the mean time the ACPI table needs
to be fixed as follow:

Device (NFC1)
{
    Name (_ADR, Zero)  // _ADR: Address
    Name (_HID, "SMO2101")  // _HID: Hardware ID
    Name (_CID, "SMO2101")  // _CID: Compatible ID
    Name (_DDN, "SMO NFC")  // _DDN: DOS Device Name
    Name (_UID, One)  // _UID: Unique ID
    Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
    {
        Name (SBUF, ResourceTemplate ()
        {
             I2cSerialBus (0x0008, ControllerInitiated, 400000,
