Replace Chromebook mentions with CrOS, that is more generic

Not all CrOS devices are Chromebooks (laptops) or run on ARM, not all RK3288
CrOS devices are Chromebooks, either.

We want to support more CrOS devices, including some that are not Chromebooks,
such as the ASUS Chromebit!

+Subject: [PATCH] chromeos: Allow disabling vboot firmware verification when
+ ChromeOS is enabled
+
+Some ChromeOS bindings might be wanted without using vboot verification, for
+instance to boot up depthcharge from the version of Coreboot installed in the
+write-protected part of the SPI flash (without jumping to a RW firmware).
+
+Vboot firmware verification is still selected by default when ChromeOS is
+enabled, but this allows more flexibility since vboot firmware verification is
+no longer a hard requirement for ChromeOS (that this particular use case still
+allows booting ChromeOS).
+
+In the future, it would make sense to have all the separate components that
+CONFIG_CHROMEOS enables have their own config options, so that they can be
+enabled separately.
