Hannes Schmelzer c0eaffa039 spi: omap3: fix claim/release bus within DM
The claim/release bus function must not reset the whole SPI core because
settings regarding wordlen, clock-frequency and so on made by
set_wordlen, set_mode, set_speed get lost with this action. Resulting in
a non-functional SPI.

Without DM the failure didn't came up since after the spi_reset within
claim bus all the setup (wordlen, mode, ...) was called, in DM they are
called by the spi uclass.

We change now the things as following for having a working SPI instance
in DM:

- move the spi_reset(...) to the probe call in DM for having a known
hardware state after probe. Without DM we don't have a probe call, so we
issue the reset as before during the claim_bus call.

- in release bus we just reset the modulctrl to the reset-value (spi-
slave)
