STPMIC1 is used by the secure world to driver the system low power
sequences. Since these sequences are executed in unpaged context,
the driver gets the configuration from the DTB during the initialization
and provides optimized functions to load target configuration at
runtime.
This change makes STPMIC1 driver to call the memory footprint optimized
function stm32_i2c_read_write_membyte() for I2C transfer instead of
generic stm32_i2c_mem_read()/stm32_i2c_mem_write(). This is more
suitable to OP-TEE pager constraints on the platform.
This changes removes now unused STPMIC1_I2C_TIMEOUT_US.
