Subject: [PATCH] spi: spidev_test: Remove hidden temporary file when make clean

In the current code, it only removes *.o and .*.o.d file when make clean,
there still exists useless .*.o.cmd file, just remove it.

Without this patch:

[yangtiezhu@...ux spi]$ make
[yangtiezhu@...ux spi]$ make clean
[yangtiezhu@...ux spi]$ ls -1 .*.o.cmd
.spidev_fdx-in.o.cmd
.spidev_fdx.o.cmd
.spidev_test-in.o.cmd
.spidev_test.o.cmd

With this patch:

[yangtiezhu@...ux spi]$ make
[yangtiezhu@...ux spi]$ make clean
[yangtiezhu@...ux spi]$ ls -1 .*.o.cmd
ls: cannot access .*.o.cmd: No such file or directory
