Geert Uytterhoeven eb6301160d tpm: Allow compile test of GPIO consumers if !GPIOLIB 
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Christophe Ricard bf38b87108 tpm/tpm_i2c_stm_st33: Split tpm_i2c_tpm_st33 in 2 layers (core + phy) 
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.
