[U-Boot] [PATCH] arm: tegra: Fix the CPU complex reset masks

The CPU complex reset masks are not matching with the datasheet for
the CLK_RST_CONTROLLER_RST_CPU_CMPLX_SET/CLR_0 registers. For both T20
and T30 the register consist of groups of 4 bits, with one bit for
each CPU core. On T20 the 2 high bits of each group are always stubbed
as there is only 2 cores.
