With this change driver will benefit from existing phylib and thus
custom phy functionality implemented in the driver will go away:
* Instantiation of the driver is now much shorter - 2 parameters
instead of 4.
* Simplified phy management/functoinality in driver is replaced with
rich functionality of phylib.
* Support of custom phy initialization is now done with existing
"board_phy_config".
Note that after this change some previously used config options
(driver-specific PHY configuration) will be obsolete and they are simply
substituted with similar options of phylib.
For example:
* CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
by default.
* CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
automatically the first discovered on MDIO bus phy will be used
I believe there's no need now in "doc/README.designware_eth" because
user only needs to instantiate the driver with "designware_initialize"
whose prototype exists in "include/netdev.h".

In SPEAr, some of the configuration flags eg. CONFIG_SPEAR_EMI, were given value
"1", which isn't required. Define the flags without assigning any value

In SPEAr configuration files, unnecessary paranthesis are used in some
\#defines. Remove them as they serve no purpose

This patch modifies the default environment variables as:
1. Default bootargs:
- console=ttyAMA0,115200
- For environment present in NOR flash
root=/dev/mtdblock3
- For environment present in NAND flash
root=/dev/mtdblock7
- Removes "mem=" option
2. Introduces CONFIG_EXTRA_ENV_USBTTY as default usbtty env var even when usbtty
is not selected
3. Add default definitions for nfsboot and ramboot
4. Add a new default environment variable(CONFIG_EXTRA_ENV_UNLOCK) for SPEAr310
and SPEAr320
Signifacance of CONFIG_EXTRA_ENV_USBTTY:
This environment variable is important for flashing utility to work. So if
somebody accidently erases the env sector then also this variable must be
preserved so that flashing utility functions properly.
Signifacance of CONFIG_EXTRA_ENV_UNLOCK:
This env variable is read by the cfi driver to unlock all flash sectors. This
is necessary because the Parallel NOR flash connected on the spear310 and
spear320 boards, M28W64, has all its sectors in locked state at reset and these
have to be unlocked explicitly before being erased or written.

This patch adds options for all the below mentioned configurations and
subsequently renames the include/configs/spearxxx.h files to spear3xx_evb.h,
spear6xx_evb.h etc to depict evaluation board configuration.
SPEAr3xx and SPEAr6xx boards can be compiled in following configurations
1. Environment placed in NAND
2. Console on usb device
3. Console on usb device with environment placed in NAND
4. SPEAr310 and SPEAr320 support environment variables in parallel
NOR flash.
