Some CPUs can speculate past an ERET instruction and potentially perform
speculative accesses to memory before processing the exception return.
Since the register state is often controlled by a lower privilege level
at the point of an ERET, this could potentially be used as part of a
side-channel attack.
This patch emits an SB sequence after each ERET so that speculation is
held up on exception return.

This patch adds the qurik to use busrt transfers only
for pl330 controller, even for request with a length of 1.
Although, the correct way should be: if the peripheral request
length is 1, the peripheral should use SINGLE request, and then
notify the dmac using SINGLE mode by src/dst_maxburst with 1.
For example, on the Rockchip SoCs, all the peripherals can use
SINGLE or BURST request by setting GRF registers. it is possible
that if these peripheral drivers are used only for Rockchip SoCs.
Unfortunately, it's not, such as dw uart, which is used so widely,
and we can't set src/dst_maxburst according to the SoCs' specific
to compatible with all the other SoCs.
So, for convenience, all the peripherals are set as BURST request
by default on the Rockchip SoCs. even for request with a length of 1.
the current pl330 driver will perform SINGLE transfer if the client's
maxburst is 1, which still should be working according to chapter 2.6.6
of datasheet which describe how DMAC performs SINGLE transfers for
a BURST request. unfortunately, it's broken on the Rockchip SoCs,
which support only matching transfers, such as BURST transfer for
BURST request, SINGLE transfer for SINGLE request.
Finaly, we add the quirk to specify pl330 to use burst transfers only.

According to the datasheet of pl330:
Example 2-1 Using DMAGO with the debug instruction registers
1. Create a program for the DMA channel
2. Store the program in a region of system memory
3. Poll the DBGSTATUS Register to ensure that the debug is idle
4. Write to the DBGINST0 Register
5. Write to the DBGINST1 Register
6. Write zero to the DBGCMD Register
so, we should make sure the debug is idle before step 4/5/6, not
only step 6. if not, there maybe a risk that fail to write DBGINST0/1.
