[2/2] powerpc: Add ppc64le and ppc64_book3e allmodconfig targets

Similarly as we just did for 32-bit, add phony targets for generating
a little endian and Book3E allmodconfig. These aren't covered by the
regular allmodconfig, which is big endian and Book3S due to the way
the Kconfig symbols are structured.

Is book3e allmodconfig not seen/used very much?

Besides the patches that I have already sent, I am seeing a build problem
with ppc64_book3e_allmodconfig, where we have:

CONFIG_USB_PHY=y
CONFIG_FSL_USB2_OTG=y
but
CONFIG_USB_OTG_FSM=m

In drivers/usb/phy/Kconfig, FSL_USB2_OTG depends on USB_OTG_FSM (among
other things), but!  FSL_USB2_OTG is a bool symbol, depending on a
tristate symbol.  This often causes problems.  In this case it causes errors
with a builtin driver trying to use symbols that are built in a loadable module:

Seems so :)

Do we just need something like?

diff --git a/drivers/usb/phy/Kconfig b/drivers/usb/phy/Kconfig
