earlier commits have broken compilation of
tusb6010 glue layer, fix it.

This will make things simpler when choosing which
glue layer to compile. It avoids a lot of magic
around the "default" Kconfig option and lets the
user choose what exactly s/he wants to compile.

The new MUSB power code needs musb_read_txhubport() to
return a value (so stub it as 0 like the other Blackfin
hub funcs).

The recent commit "usb: musb: Add context save and restore support" added
some stubs for the Blackfin code so things would compile, but it also
added a bunch of warnings due to missing return statements.

The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY.
However, it has no ULPI support - so there are no registers at all.
That means accesses to ULPI_BUSCONTROL have to be abstracted away
like other MUSB registers.

This fixes building for Blackfin parts again.

All current Blackfin parts are using RTL v1.9, but they don't expose the
hardware registers to probe this dynamically.  So hardcode the version to
v1.9 for now.

Need to move the local hwvers related defines higher up in the header so
that sub-musb headers may utilize them.

Adding support for MUSB register save and restore during system
suspend and resume.

Changes:
        - Added musb_save/restore_context() functions
        - Added platform specific musb_platform_save/restore_context()
          to handle platform specific jobs.
        - Maintaining BlackFin compatibility by adding read/write
          functions for registers which are not available in BlackFin

Tested system suspend and resume on OMAP3EVM board.

Some of the board might use external Vbus power supply on musb
interface which would require to program ULPI_BUSCONTROL register.

Adding 'extvbus' flag which can be set from such boards which will
be checked at musb driver files before programming ULPI_BUSCONTROL.

The Blackfin version of musb_read_target_reg_base() returns a u16 when the
common code expects a (void __iomem *), so update the Blackfin function to
return the right value.  This fixes the compile warning:

The Blackfin port doesn't support HAVE_CLK and the musb driver works fine
with support stubbed out, so take the existing Blackfin clk stubs and move
them to common musb code so we can drop the Kconfig dependency.

INDEX register has to be set to '0' before reading
CONFIGDATA register which is only present in TI musb
platforms.

Currently the default register access mode is set to
FLAT_MODE thus INDEX register is not getting set
properly with musb_ep_select() which is just a nop
operation in FLAT_MODE.This invalid register read is
causing module reinset failure.

Fixing the issue by moving INDEX register write part to
musb_read_configdata() function itself.
