In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.
Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

When st33zp24_i2c_acpi_request_resources() gets called we
already know that the entries in ->acpi_match_table have matched ACPI ID
of the device.
In addition I2C client pointer cannot be NULL in any case (otherwise I2C
core would not call ->probe() for the driver in the first place).
Drop the two useless checks from the driver.

tpm_i2c_stm_st33 is a TIS 1.2 TPM with a core interface which can be used
by different phy such as i2c or spi. The core part is called st33zp24 which
is also the main part reference.
include/linux/platform_data/tpm_stm_st33.h is renamed consequently.
The driver is also split into an i2c phy in charge of sending/receiving
data as well as managing platform data or dts configuration.
