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.
