tests: Use real spi_send_command for all tests except spi25.c

At the moment one test (spi25.c) uses wrap of spi_send_command, and
all other existing tests don't care about this function (don't call
it at all). However in the next patch a new test in introduced, which
needs a real spi_send_command.

Following the approach "don't mock unless it is strictly necessary",
all tests that don't care go into real function bucket.

A declaration for __real_spi_send_command is needed for visibility,
this way wrap function can redirect to real function for all other
tests except spi25.c.

Additionally, wrap function moves below mock_chip, so that mock_chip
is visible inside wrap.
