Poll for a well defined time in musb_init. The current counting loop
takes too short for some devices. Tested on OMAP3 with a rather slowish
memory stick.

Since 2011 barebox' of_device_id struct uses unsigned long type for data field:
struct of_device_id {
char *compatible;
unsigned long data;
};
Almost always struct of_device_id.data field are used as pointer
and need 'unsigned long' casting.
E.g. see 'git grep -A 4 of_device_id drivers/' output:
drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = {
drivers/ata/sata-imx.c- {
drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci",
drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6,
drivers/ata/sata-imx.c- }, {
Here is of_device_id struct in linux kernel v4.0:
struct of_device_id {
char name[32];
char type[32];
char compatible[128];
const void *data;
};
Changing of_device_id.data type to 'const void *data' will increase
barebox' linux kernel compatibility and decrease number of 'unsigned
long' casts.
Part of the patch was done using the 'coccinelle' tool with the
following semantic patch:

Use container_of instead of dev->priv pointer. dev->priv is
used by the musb core layer (which maybe should not be the
case, but using container_of is good anyway).

musb_barebox.c contains code that is only ever used if CONFIG_MUSB_HOST
is set. Building it uncoditionally breaks the build depending on the link
order.

This changes the MUSB support from the original Kernel state to
be usable with barebox. Tested on a custom board and the Beaglebone
Black. The host port on the Beaglebone works, the OTG port works
in device mode, but not yet in host mode.
Based on the initial MUSB port from Rolf Evers Fischer.

This adds the necessary files from the MUSB driver directly from Linux
3.17-rc5. No changes to the original files have been made so far.
