The previous commit (6b8fd11) gated smbus and smbus_sbs behind PX4_PLATFORM=="nuttx" to prevent clang-tidy errors on SITL, but these libraries depend on device::I2C which has a POSIX implementation (posix/I2C.cpp). Linux boards like bluerobotics_navigator (armhf) and emlid_navio2 (aarch64) enable CONFIG_DRIVERS_BATT_SMBUS, which depends on drivers__smbus — causing CMake to fail with "non-existent target". Move smbus and smbus_sbs back to unconditional add_subdirectory() so they are available on all platforms. Keep mcp_common gated behind NuttX since it includes px4_platform/gpio/mcp.hpp (NuttX-only GPIO headers). Re-add src/lib/drivers/smbus to the Makefile clang-tidy exclude list since the SITL compilation database lacks the I2C platform headers needed for analysis.
