Subject: [PATCH 1/4] spi: mt7621: Fix an error message in mt7621_spi_probe()

'status' is known to be 0 at this point. The expected error code is
PTR_ERR(clk).

Switch to dev_err_probe() in order to display the expected error code (in a
human readable way).
This also filters -EPROBE_DEFER cases, should it happen.

Fixes: 1ab7f2a43558 ("staging: mt7621-spi: add mt7621 support")
