[PATCH 2/3] mfd: rk8xx-core: Configure `rk808-clkout2` function

[Rudraksha Gupta via B4 Relay <devnull+guptarud.gmail.com@kernel.org>]

From: Kamil Trzciński <ayufan@ayufan.eu>

While the Wifi and Bluetooth chip are defined in the Pinephone Pro's
DTS, it actually isn't able to be used. Let's define rk808-clkout2 so
that userspace can actually interact with Wifi and Bluetooth
