Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

Accessing the higher vidtcon variables using pointer arithmetic from the
lower address FIMD_CTRL struct is undefined behaviour, since pointers
manipulations are not allowed outside the objects they point to. The
standard-blessed way is to perform the arithmetic using integer
addresses first, and then convert that to a pointer. The end result is
the same, but avoids the risk of unsafe optimizations from an
over-zealous compiler.

Consider the following assignment:
u64 = s32
For positive values this is fine, but if the s32 is negative, it will be
sign-extended in the conversion to a very large unsigned integer. This
manifests itself in two ways in the following code:
First, gpu_pipe{a,b}_port_select are defined as int, and can have the
values 1 or 2. In the case when they have the value 2, the shift 2 << 30
will be a negative number, making it susceptible to the sign-extension
problem above. Change these variables to something more reasonable like
a uint8_t, which is unsigned.
Second, in any bit shift, any variable with width less than an int will
be implicitly promoted to an int before performing the bit shift.
For example, the variable gpu_pipea_power_on_delay is a uint16_t, and if its
highest bit is set, the shift gpu_pipea_power_on_delay << 16 will become
negative, again introducing the above problem. To prevent this, cast all
smaller variables to a u32 before the shift, which will prevent the
implicit promotions and sign extensions.
