From: Tudor Ambarus <tudor.ambarus@microchip.com>

The sam9x60 qspi controller uses 2 clocks, one for the peripheral register
access, the other for the qspi core and phy. Both are mandatory.

Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>
---
v3: "pclk" was made mandatory in previous patch. Reword clock
descriptions.
v2:
- make "pclk" mandatory even for sama5d2. Unnamed clk will be
supported in the driver.
- drop unneeded example
