SF_DUAL_FLASH claims to enable support for SF_DUAL_STACKED_FLASH and
SF_DUAL_PARALLEL_FLASH. But, in current U-Boot code, grepping for above
enums yield no user and therefore support seems to be incomplete. Remove
these configs so as to avoid confusion.

-SPI/QSPI Dual flash connection modes:
-=====================================
-
-This describes how SPI/QSPI flash memories are connected to a given
-controller in a single chip select line.
-
-Current spi_flash framework supports, single flash memory connected
-to a given controller with single chip select line, but there are some
-hw logics(ex: xilinx zynq qspi) that describes two/dual memories are
-connected with a single chip select line from a controller.
-
-"dual_flash" from include/spi.h describes these types of connection mode
-
-Possible connections:
---------------------
-SF_SINGLE_FLASH:
-       - single spi flash memory connected with single chip select line.

-
-       - two memory flash devices should has same hw part attributes (like size,
-         vendor..etc)
-       - Configurations:
-               on LQSPI_CFG register, Enable TWO_MEM[BIT:30] on LQSPI_CFG
-               Enable U_PAGE[BIT:28] if U_PAGE flag set - upper memory
-               Disable U_PAGE[BIT:28] if U_PAGE flag unset - lower memory
-       - Operation:
-               accessing memories serially like one after another.
-               by default, if U_PAGE is unset lower memory should accessible,
-               once user wants to access upper memory need to set U_PAGE.
-
-SPI_FLASH_CONN_DUALPARALLEL:
-	- dual spi/qspi flash memories are connected with a single chipselect
-	  line and these two memories are operating parallel with separate buses.
-	- xilinx zynq qspi controller has implemented this feature [1]
-

-  |		|---------------------->|		|
-  +-------------+			+---------------+
-
-	- two memory flash devices should has same hw part attributes (like size,
-	  vendor..etc)
-	- Configurations:
-		Need to enable SEP_BUS[BIT:29],TWO_MEM[BIT:30] on LQSPI_CFG register.
-	- Operation:
-		Even bits, i.e. bit 0, 2, 4 ., of a data word is located in the lower memory
-		and odd bits, i.e. bit 1, 3, 5, ., of a data word is located in the upper memory.
-
-Note: Technically there is only one CS line from the controller, but
-zynq qspi controller has an internal hw logic to enable additional CS
-when controller is configured for dual memories.
