ALSA: hda/tegra: Align BDL entry to 4KB boundary
[ Upstream commit 8d44e6044a0e885acdd01813768a0b27906d64fd ]
AZA HW may send a burst read/write request crossing 4K memory boundary.
The 4KB boundary is not guaranteed by Tegra HDA HW. Make SW change to
include the flag AZX_DCAPS_4K_BDLE_BOUNDARY to align BDLE to 4K
boundary.
