ARM: davinci_all_defconfig: Enable some UBI modules

This enables UBI+UBIFS to handle the NAND MTDs, including the useful MTD_UBI_BLOCK.

2.9.2

The davinci boards don't have their clocks in DT yet and getting a clock with a null con_id will fail, unless registering them as clk_lookups. This registers the aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
'CLK(NULL, "aemif", &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via the ti-aemif memory driver code.

This patch was originally patch 1/4 of the series
"Add DT support for NAND to LCDK via ti-aemif" from which two other patches have already applied in Sekhar's tree.
Sekhar, please note that commit 31e3a881 ("ARM: dts: da850,da850-evm:
Add an aemif node and use it for the NAND") of your tree depends on this change.

Thanks,
Karl

I sent this email twice, let's discard this one.
