The SYS_BOOT-based fallback shouldn't only check for one of the conditions of
use and then let the switch/case handle each boot device without enforcing the
conditions for each type of boot device again.
For instance, this behaviour would trigger the fallback for UART when
BOOT_DEVICE_UART is defined, CONFIG_SPL_YMODEM_SUPPORT is enabled (which should
be a show-stopper) and e.g. BOOT_DEVICE_USB is enabled and not
CONFIG_SPL_USB_SUPPORT.
Separating the logic for USB and UART solves this.
In addition, this adds support for more peripheral devices (USBETH and CPGMAC)
to the fallback mechanism. Note that the USBETH boot device should always be
different from the USB boot device (each should match a different bootrom
handoff case).

DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.
Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.
NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.
