dt-bindings: Fix SPI and I2C bus node names in examples

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:

git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'

With this, a few errors in examples were exposed and fixed.

Enabling qca,ar71xx causes a warning, so let's fix the node names:

dt-bindings: net: nfc: s3fwrn5: Change I2C interrupt trigger type

Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING
for stable NFC I2C interrupt handling.
Samsung's NFC Firmware sends an i2c frame as below.
1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c
frame to send.
2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the
GPIO low.
NFC driver's i2c interrupt handler would be called in the abnormal case
as the NFC FW task of number 2 is delayed because of other high priority
tasks.
In that case, NFC driver will try to receive the i2c frame but there isn't
any i2c frame to send in NFC.
It would cause an I2C communication problem. This case would hardly happen.
But, I changed the interrupt as a defense code.
If Driver uses the TRIGGER_RISING instead of the LEVEL trigger,
there would be no problem even if the NFC FW task is delayed.
