For the stm32 mcu with a CONDRST bit in its RNG_CR
for conditioning Soft Reset, the driver must wait for
the bit to be 0 after disabling. This could take
about 2 AHB clock cycles + 2RNG clock cycles.

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

This is a follow-up to commit e1c0a494b3.
The `tca954x_transfer()` function cannot call `i2c_transfer_dt()`,
because the I2C device address used in the transaction must be the one
passed as the `addr` parameter, not the address of the TCA954xA switch
itself. Hence, this commit restores the call to `i2c_transfer()`.

Fix a call that writes Register 29 - Accelerometer Configuration 2.

According to the BME680 datasheet, only the spi_mem_page bit can be
changed in its 8-bit register. Therefore we shouldn't just write 0s
to the remaining bits, but update the register content in read-modify-write
fashion instead.
Rework the bme680_set_mem_page(), bme680_init() and register-access
macros.
