The packet length of DCS long write packet should not be added with 1
when constructing long write packet.
Fix this.

The formula in the BSP kernel indicates that a 16-byte overhead is used
when sending the HFP. However, this value is currently set to 6 in the
sun6i_mipi_dsi driver, which makes some panels flashing.
Fix this overhead value.

This breaks the similar pattern to other formulas, so restoring the
original formula is more proper.

Currently, when allocating the memory for BO by Mesa, the lima kernel
driver set only GFP_DMA32 flag; and this allocation may fail when the
memory is relatively adequate, thus retrying is needed.
Add the GFP flags for retrying memory allocation.
