porting guidelines: fix bad link
Change the link to point to the correct page when referring to
configuration and compile time flags. In the same section fix the bullet
list so it renders correctly.

**conf.mk**
This is the device specific makefile where you define configurations unique to
-your platform. This mainly comprises two things: - OP-TEE configuration
-variables (``CFG_``), which may be assigned values in two ways. ``CFG_FOO ?=
-bar`` should be used to provide a default value that may be modified at compile
-time. On the other hand, variables that must be set to some value and cannot be
-modified should be set by: ``$(call force,CFG_FOO,bar)``. - Compiler flags for
-the TEE core, the user mode libraries and the Trusted Applications, which may be
-added to macros used by the build system. Please see `Platform-specific
-configuration and flags`_ in the build system documentation.

It is recommended to use a existing platform configuration file as a starting
point. For instance, `core/arch/arm/plat-hikey/conf.mk`_.
