nfc: st21nfca: i2c: Change ST21NFCA_GPIO_NAME_RESET to match DT

Since
commit 10cf4899f8 ("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, "SMO2100")  // _HID: Hardware ID
    Name (_CID, "SMO2100")  // _CID: Compatible ID

    Name (_UID, One)  // _UID: Unique ID

             }

             }
        })
        Return (SBUF) /* \_SB_.I2C7.NFC1._CRS.SBUF */
    }
    Method (_STA, 0, NotSerialized)  // _STA: Status
    {
        Return (0x0F)
