1. support buffer_size set by user
2. support assigned chn
3. support udma read
4. support buffer address set by userspace
Need to update test_pcie and test-pcie-ep-new.
New test command:
1. run ./test-pcie-ep-new 500 1024 chn_num buffer_address both on RC and EP first
Release buffer use dma channel number = chn_num.
if buffer_address = 0
pcie_dma_buffer_address get from DT reserved memory
else
pcie_dma_buffer_address = buffer_address
2. run ./test-pcie 1 1000 1024 1 chn_num on RC
The last "1" means enable PCIe udma read, "0" means write.
RC read from EP use dma channel number = chn_num.
3. run ./test-pcie 2 1000 1024 1 chn_num on EP
EP read from RC with offset = buffer count * buffer size.
4. check version by:
cat /sys/kernel/debug/pcie/pcie_trx | grep version
5. 1024 means set buffer size to 1MB.

When enter low temperature mode, system monitor update opp table, then
check and change the current voltage for cpu, but now the opp voltage
inside cpu_opp_helper() may be old, the current voltage may be changed
back to old value. Move the volt_adjust_mutex out of dev_pm_opp_set_rate()
so that the opp voltage inside cpu_opp_helper() will be latest.

If read multiple channels at the same time, channel 1 will
error, add assert when start saradc as a workaround.

Remove a regulator-fixed node without gpio enable pin from evb dtsi,
move them to next level board dt file.
The vcc3v3_lcd0_n regulator is a software virtual regulator for camera
module to push high/low level from a gpio but through regulator
enable/disable.

tips:
1. this driver supports one or multi-core device.
2. the multi-core method is the same as vepu2.

tips:
1. CCU is short-name for the central control unit.
2. In multi-core processing, CCU is used to balance the scheduling of
each core.
3. The scheduling criteria are the number of tasks in the current queue
and the total number of completed tasks.
