PD#159028: char_dev: extend dynamic allocation of majors into a higher range
We've run into problems with running out of dynamicly assign char
device majors particullarly on automated test systems with
all-yes-configs. Roughly 40 dynamic assignments can be made with such
kernels at this time while space is reserved for only 20.
Currently, the kernel only prints a warning when dynamic allocation
overflows the reserved region. And when this happens drivers that have
fixed assignments can randomly fail depending on the order of
initialization of other drivers. Thus, adding a new char device can cause
unexpected failures in completely unrelated parts of the kernel.
This patch solves the problem by extending dynamic major number
allocations down from 511 once the 234-254 region fills up. Fixed
majors already exist above 255 so the infrastructure to support
high number majors is already in place. The patch reserves an
additional 128 major numbers which should hopefully last us a while.
Kernels that don't require more than 20 dynamic majors assigned (which
is pretty typical) should not be affected by this change.

PD#158373: mm: check pfn overflow for low memory platform
On ARM64 platform, when vmemmap_populate is called for reserve
memory for struct page, it reserved based 1GB a loop. And 16MB
memory will be reserved at least. This caused memory waste if
total RAM is less than 1GB.
Basically reserve memory size for struct page is calculated by:
reserve size = sizeof(struct page) * number of pages.
For example, currently struct page is 64 bytes on ARM64. A page
is 4KB. So reserve size table can be:
Memory | page count | reserve size(bytes)
-------------------------------------------------
128MB | 32768 | 2097152(2MB)
256MB | 65536 | 4194304(4MB)
512MB | 131072 | 8388608(8MB)
Note, This reserve is aligned at 2MB.

PD#157965: pinctrl: define the pinmux with the same format.
there are two different pin controllers in Meson Soc Series, one of
them uses continuous 4-bit register to select function for each pin
(Eg: AXG and next), the other use indefinite bits that maybe from
different registers (Eg: Before AXG and GXLX)
previously, the driver use two different format to define the pinmux,
as follows:
[1] Before AXG and GXLX:
mux {
groups = "uart_ao_tx_a", "uart_ao_rx_a";
function = "uart_ao_a";
}
[2] AXG and next
mux {
pins = "GPIOAO_0", "GPIOAO_1";
function = "uart_ao_a";
}
which is a little confusing，and in this patch define the pinmux with
one format[1].

PD#157965: pinctrl: separate soc drivers
When meson pinctrl is enabled, all meson platforms pinctrl drivers are
built in the kernel, with a significant amount of data.
This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.
This change makes 3 pinctrl drivers (1 per SoC) out the original single
driver, allowing to compile and ship only the ones required.

4) remove the GPIO IRQ Controller in AO domain
note that the driver does not support for detecting the double-edge signal
through the pin，if you have related needs, please consider using polling.
