Subject[PATCHv2] drivers: optee: fix i2c build issue
Date
When the optee driver is compiled into the kernel while the i2c core
is configured as a module, the i2c symbols are not available.

This commit addresses the situation by disabling the i2c support for
this use case while allowing it in all other scenarios:

i2c=y, optee=y
i2c=m, optee=m
i2c=y, optee=m
i2c=m, optee=y (not supported)

Reported-by: kernel test robot <lkp@intel.com>

v2: uses IS_REACHABLE instead of macro combination
