d291d8235b configs: Fixup some CPSW-related items
- For am335x_pdu001 we do not want the CPSW driver, drop it
- Re-sync the defconfig for am43xx_evm_rtconly as it came in after the
  patch that converted CPSW to Kconfig was posted but before it was
  applied.
- Drop empty section / comments from pengwyn
- Drop empty section / comments from baltos and drop unused
  CONFIG_SPL_NET_VCI_STRING (it does not enable CONFIG_SPL_NET_SUPPORT
  currently and SPL_NET_VCI_STRING has been migrated already).

7619badb9c ARM: AM43xx: Add support for RTC only + DDR in self-refresh mode
Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers
for wakeup from RTC-only mode with DDR in self-refresh. Parse these
registers during SPL boot and jump to the kernel resume vector if the
device is waking up from RTC-only modewith DDR in Self-refresh.

The RTC scratch register layout used is:

SCRATCH0 : bits00-31 : kernel resume address
SCRATCH1 : bits00-15 : RTC magic value used to detect valid config
SCRATCH1 : bits16-31 : board type information populated by bootloader

During the normal boot path the SCRATCH1 : bits16-31 are updated with
the eeprom read board type data. In the rtc_only boot path the rtc
scratchpad register is read and the board type is determined and
correspondingly ddr dpll parameters are set. This is done so as to avoid
costly i2c read to eeprom.

RTC-only +DRR in self-refresh mode support is currently only enabled for
am43xx_evm_rtconly_config.
This is not to be used with epos evm builds.
