[U-Boot] [PATCH] ARM: tegra: increase buffer size and sys args num

[Michael Scott <hashcode0f@gmail.com>]

From: Bryan Wu <pengw@nvidia.com>

Tegra kernel booting needs a long bootargs command line.

Default value of CONFIG_SYS_CBSIZE is too small to printf out the
long command line and will cause system panic.

Default value of CONFIG_SYS_MAXARGS is too small to setenv bootargs
as the long command line, then kernel won't boot without the complete
bootargs.

Increase this 2 config options solve this problem.
