This isn't adding a node -- it's changing values.  If the old ones were
wrong, explain that in the changelog.

Also, p2020si-post.dtsi already adds interrupts to this node (and it
contains one more interrupt than the above), and it includes
pq3-etsec1-timer-0.dtsi which contains the compatible and reg (and
interrupts with two specifiers).  Probably all of these should be using
pq3-etsec1-timer-0.dtsi and only specifying the board-specific values.

Please don't use hex for numbers that make more sense as decimal.
[Lu Yangbo-B47093] The hex value is register value, I think it's better to use hex.

Whether it goes into a register doesn't matter.  Hex values are useful
for values which are subdivided into various bitfields, or whose hex
representation is simpler than decimal.  I'm not familiar with the
details of this hardware, but I doubt the former is the case for
0x3b9ac9fb == 9999999995 or 0x18696 == 99990.
