tpm: tpm_tis_spi: Cleanup includes

Some of these includes aren't used, for example of_gpio.h and freezer.h,
or they are missing, for example kernel.h for min_t() usage. Add missing
headers and remove unused ones so that we don't have to expand all these
headers into this file when they're not actually necessary.
