[U-Boot,1/3] am43xx: Remove ethboot / usbhost_boot variants

The intention of having aaa_evm_xxx_defconfig variants is to allow
building for useful but non-default cases that cannot be easily done
with the standard aaa_evm_defconfig file.  In this case, we get rid of
usbhost_boot as SPL_TEXT has been in OCMC RAM for a while now, so this
can be included in the default.  We get rid of ethboot as it's fine to
have the environment in someplace that's not available and the default
will be used.  Further, now that environment location is in Kconfig it's
reasonable to expect a user of this feature to optimize their use-case
if needed.

SPL_TEXT for default boot is 0x402f0400
SPL_TEXT for usb host boot is 0x40300350 as ROM uses the initial portion
for DMA when copying from USB. Initially we thought of moving SPL_TET
for default boot to 0x40300350 but this will break UART boot as it has
to be 0x402f0400 for it. So I guess we cannot remove usb host boot
defconfig.

With DM_ETH enabled, it enforces to have DM for usb peripheral for usb
rndis boot, which is not supported yet. Vignesh is currently working on
it. I guess once it is done, ethboot_defocnfig can be removed.

So $patch breaks both usb host and ethboot.

Thanks and regards,
Lokesh

Has ethboot been tested with this patch because previously
ethboot_defconfig did not imply DM_ETH?

Aw, ok, thanks!
