pcm051/igep0033: Supply bd_ram_ofs for cpsw driver

Since 2bf36ac638ab2db9f0295aa47064976eeebf80c1 the BD ram address is
not hardcoded inside cpsw driver any more. Platforms have to supply
their bd_ram_ofs in the platform data to the driver. This commit does
this for pcm051 and igep0033 boards.

usb: Fix error handling in musb_hcd.c

The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success
containing the value 0, 1 or -1. This patch changes the return type to an
int to accommodate the negative return values.

These functions are used in the file using calls such as if (!wait_until...
Where a -1 is returned it is mishandled and treated as success instead of
a CRC error. This patch addresses this.

sf: Divide spi_flash into multiple parts

Divided the spi_flash framework into mutiple parts for
- spi_flash.c:
        spi flash core file, interaction for spi/qspi driver to
        spi_flash framework.
- spi_flash_ops.c
        spi flash preffered operations, erase,write and read.
- spi_flash_probe.c
        spi flash probing, easy to extend probing functionality.

This change will support to extend the functionality in a
proper manner.
