rp2040: use 4MHz as default frequency for SPI
...
This matches other SPI implementations. I think the original value of
115200 was from a confusion with UART.

rp2040: remove SPI deadline
...
Removing it improves SPI performance by about 20% for me (updating the
display of a Gopher Badge).

rp2040: remove SPI DataBits property
...
As discussed on Slack, I believe this property does more harm than good:
* I don't think it's used anywhere. None of the drivers use it.
* It is not fully implemented. While values <= 8 might work fine,
values larger than 8 result in extra zero bits (instead of anything
sensible).
* Worse, it doesn't return an error when it's out of range. This is
not an optional property: if the SPI peripheral doesn't support a
particular number of bits, it should return an error instead of
silently limiting the number of bits. This will be confusing to
users.
Therefore, I propose we drop it. Maybe there are good uses for it
(perhaps for displays that use big endian 16-bit values?), but without a
good use case like a driver in tinygo.org/x/drivers, I think it's more
trouble than it's worth.

nrf: fix memory issue in ADC read
...
There was a very subtle bug in the ADC read code: it stores a pointer to
a variable in a register, waits for the hardware to complete the read,
and then reads the value again from the local variable. Unfortunately,
the compiler doesn't know there is some form of synchronization
happening in between.
This can be fixed in roughly two ways:
* Introduce some sort of synchronization.
* Do a volatile read from the variable.
I chose the second one as it is probably the least intrusive. We
certainly don't need atomic instructions (the chip is single threaded),
we just need to tell the compiler the value could have changed by making
the read volatile.

all: use unsafe.Add instead of unsafe.Pointer(uintptr(...) + ...)
...
We have an optimization for this specific pattern, but it's really just
a hack. With the addition of unsafe.Add in Go 1.17 we can directly
specify the intent instead and eventually remove this special case.
The code is also easier to read.
