i2c: tegra: Fix i2c-tegra DMA config option processing

Tegra processors prior to Tegra186 used APB DMA for I2C requiring
CONFIG_TEGRA20_APB_DMA=y while Tegra186 and later use GPC DMA requiring
CONFIG_TEGRA186_GPC_DMA=y.

The check for if the processor uses APB DMA is inverted and so the wrong
DMA config options are checked.

This means if CONFIG_TEGRA20_APB_DMA=y but CONFIG_TEGRA186_GPC_DMA=n
with a Tegra186 or later processor the driver will incorrectly think DMA is
enabled and attempt to request DMA channels that will never be availible,
leaving the driver in a perpetual EPROBE_DEFER state.
