Simon Glass f3998fdc4d env: Rename environment.h to env_internal.h
This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.

Rename this file and add a comment at the top to indicate its internal
nature.

Overview
--------
P1022ds is a Low End Dual core platform supporting the P1022 processor
of QorIQ series. P1022 is an e500 based dual core SOC.


Pin Multiplex(hwconfig setting)
-------------------------------
Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex
via hwconfig, i.e:
'setenv hwconfig usb2' to enable USB2 and disable eTsec2
'setenv hwconfig tdm' to enable TDM and disable Audio
'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz)
 and disable TDM
'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio
'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources
 is 11MHz), disable eTsec2 and TDM

Warning: TDM and AUDIO can not enable simultaneous !
and AUDIO codec clock sources only setting as 11MHz or 12MHz !
'setenv hwconfig 'audclk:12;tdm'	--- error !
'setenv hwconfig 'audclk:11;tdm'	--- error !
'setenv hwconfig 'audclk:10'		--- error !
