Cortex-M archs support option memory protection unit (MPU). MPU is used
to set the memory types, attributes, access permissions for different regions,
cache policies of the device.
e.g. using MPU it is possible to configure memory region as device memory
or strongly ordered, memory attributes like execute never, cache policies
like write-back or write-through.

There are 3 regions used by rk3399 ATF:
- bl31 code, located at 0x10000;
- cortex-m0 code and data, located at 0xff8c0000;
- bl31 data, located at 0xff8c1000 ~ 0xff8c4000;
SPL_TEXT_BASE starts from 0xff8c2000, we need to reserve memory
for ATF data, or else there will be memory corrupt after SPL
loads the ATF image.

This commit adds support for the pin-configuration of the SPI5
controller of the RK3399 through the following changes:
* grf_rk3399.h: adds definition for configuring the SPI5 pins
in the GPIO2C group
* periph.h: defines PERIPH_ID_SPI3 through PERIPH_ID_SPI5
* pinctrl_rk3399.c: adds the reverse-mapping from the IRQ# to
PERIPH_ID_SPI5; dispatches PERIPH_ID_SPI3
through SPI5 to the appropriate pin-config
function; implements the pin-configuration
for PERIPH_ID_SPI5 using the GPIO2C group
