Originally, the DLEVEL selects the debug level within the sequencer code,
but only displays the messages on that particular debug level. Tweak the
handling such that for particular debug level, debug messages on that
level and lower are displayed. This allows better regulation of debug
message verbosity.

On the H3 we need to enable the clk and de-assert the reset of the
companion to be able to talk to the actual usb host controller.
Before this commit we were also disabling the companion clk-gate /
asserting its reset on remove, causing the later remove callback of
the companion itself to (sometimes) fail with:
ERROR: USB HC reset timed out!
This commit fixes this by not disabling the companion's clk-gate nor
asserting its reset on remove.

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.
For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.
I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

Support Driver Model for fsl esdhc driver.
1. Introduce a new structure struct fsl_esdhc_priv
2. Refactor fsl_esdhc_initialize which is originally used by board code.
- Introduce fsl_esdhc_init to be common usage for DM and non-DM
- Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part.
- The original API for board code is still there, but we use
'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it.
3. All the functions are changed to use 'struct fsl_esdhc_priv', except
fsl_esdhc_initialize.
4. Since clk driver is not implemented, use mxc_get_clock to geth
the clk and fill 'priv->sdhc_clk'.
