Add support for Mobileye EyeQ5 reset controller

Hi, We follow-up the platform support series for Mobileye EyeQ5 [1] with this reset controller patch series. The registers are located in a shared register region called OLB ("Other Logic Block"). A single driver instance handles the three existing reset domains, each with their custom logic: - We busy-wait on the first two for hardware LBIST reasons (logic built-in self-test). - Domains 0 & 2 work in a bit-per-reset fashion while domain 1 works in a register-per-reset fashion. We end the series by adding the node to the platform devicetree and reset handles to the three UARTs.
