[U-Boot] [PATCH] arm: tegra: raise CONFIG_SYS_MALLOC_LEN to 32mb

[Michael Scott]

Due to a new fastboot use case and an 8mb DFU test being
added, the sys malloc limit of 4mb should be raised.

Fastboot flash of a sparse filesystem images requires
large DMA aligned allocations in the tegra_mmc driver.
When I ran fastboot flash tests on Jetson-TK1, the largest
allocation I encounted was ~26mb using a sparsed system.img
test file.

Choosing 32mb as a "safe" new limit.
