spi: tegra210-quad: Fix validate combined sequence

[ Upstream commit 047ee71ae4f412d8819e39e4b08c588fa299cfc2 ]

Check for non dma transfers that do not fit in FIFO has issue and skips
combined sequence for Tegra234 & Tegra241 which does not have GPCDMA.

Fixes: 1b8342cc4a38 ("spi: tegra210-quad: combined sequence mode")
