Add the support for the am437x xhci usb host.
The xHCI host on AM437 is connected to a usb2 phy so need to
add support to enable those clocks.

Add the support for the dra7xx xhci usb host.
dra7xx does not contain an EHCI controller so the headers
can be removed from the board file.

add support to enable those clocks.

Moving the usb/phy code from xhci-omap to the usb/phy directory
and moving the associated phy code over to the new file.
Newer TI processors adding xHCI support will have different PHY configurations
so therefore abstracting this code away will prevent messing around with the
xhci-omap file itself.

u-boot standard i2c read prototype is
i2c_read(addr, reg, 1, &buf, 1)
twl4030_i2c_read_u8(u8 addr, u8 *val, u8 reg)
does not provide consistency, so switch the prototype to be
consistent with rest of u-boot i2c operations:
twl4030_i2c_read_u8(u8 addr, u8 reg, u8 *val)

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

The twl4030 provides a PHY device for connecting a link device,
like musb, to physical connection.
This change adds the twl4030 usb registers and functions for
initializing the PHY as required by omap3.
