All RPi 1 and 2 boards used the PWM (audio out) on pin 40 and 45.
So it was easy to define them in bcm2835-rpi.dtsi. Starting with RPi 3
this wont work anymore, because it uses pin 40 and 41. Furthermore the
Zero variants doesn't have audio out.
This patch fixes this pin conflict by moving the PWM node to the board-level.
Change summary:
RPi 3 B: PWM1 45 -> 41
Zero, Zero W: PWM disabled
all other: no functional change

After commit a98d90e7d588 ("gpio: raspberrypi-exp: Driver for RPi3 GPIO
expander via mailbox service") we are able to control the rest of the
GPIOs of the RPi 3. So add all the missing parts (ACT LED,
Wifi & BT control, HDMI detect) to the DT.

The Raspberry Pi 3 B+ has the following major differences compared
to the model 3 B:
* Microchip LAN7515 (Gigabit Ethernet with integrated USB 2.0 HUB)
* Cypress CYW43455 (802.11n/ac and BT 4.2)
We need to add the USB LAN chip so the bootloader can add the MAC address.
This is necessary because there ain't an EEPROM or a valid OTP.

Subject: drm/vc4: Fix memory leak during BO teardown
During BO teardown, an indirect list 'uniform_addr_offsets' wasn't being
freed leading to leaking many 128B allocations. Fix the memory leak by
releasing it at teardown time.

Subject: serial: mvebu-uart: Fix local flags handling on termios update

Commit 68a0db1d7da2 reworked the baud rate selection, but also added
a (not so) subtle change in the way the local flags (c_lflag in the
termios structure) are handled, forcing the new flags to always be the
same as the old ones.
The reason for that particular change is both obscure and undocumented.
It also completely breaks userspace. Something as trivial as getty is
unusable:
<example>
Debian GNU/Linux 9 sy-borg ttyMV0
sy-borg login: root
root
[timeout]
Debian GNU/Linux 9 sy-borg ttyMV0
</example>
which is quite obvious in retrospect: getty cannot get in control of
the echo mode, is stuck in canonical mode, and times out without ever
seeing anything valid. It also begs the question of how this change was
ever tested.
The fix is pretty obvious: stop messing with c_lflag, and the world
will be a happier place.

The PSCI area should be reserved in Linux for PSCI operations such as
suspend/resume.
Reserve 2MiB of memory which matches the area used by ATF (BL1, BL2,
BL3x, see [1] in ATF source code). This covers all PSCI code and data
area and is 2MiB aligned, which is required by Linux for huge pages
handling.
