Fix reset to BL3-1 instructions in user guide, part 2 

Fix the instructions for resetting to the BL3-1 entrypoint in the
user guide. The BL3-1 and BL3-2 image locations changed in the fix
to ARM-software/tf-issues#100 (commit 186c1d4b). This is distinct
from the similar issue fixed in commit bfb1dd51.

Also clarify the dependence on the FVP_SHARED_DATA_LOCATION and
FVP_TSP_RAM_LOCATION build options, and tidy up the "Notes
regarding Base FVP configuration options" section.

### Notes regarding Base FVP configuration options
Please refer to these notes in the subsequent "Running on the Base FVP"
sections.
1. The `-C bp.flashloader0.fname` parameter is used to load a Firmware Image
Package at the start of NOR FLASH0 (see the "Building the Trusted Firmware"
section above).
Package at the start of NOR FLASH0 (see the "Building the Trusted Firmware"

2. Using `cache_state_modelled=1` makes booting very slow. The software will
still work (and run much faster) without this option but this will hide any
cache maintenance defects in the software.

section above).
if a Linux RAM-disk file-system is used (see the "Obtaining a root

4. Setting the `-C bp.secure_memory` parameter to `1` is only supported on
Base FVP versions 5.4 and newer. Setting this parameter to `0` is also
supported. The `-C bp.tzc_400.diagnostics=1` parameter is optional. It
instructs the FVP to provide some helpful information if a secure memory
violation occurs.
Base FVP versions 5.4 and newer. Setting this parameter to `0` is also
supported. The `-C bp.tzc_400.diagnostics=1` parameter is optional. It
instructs the FVP to provide some helpful information if a secure memory
violation occurs.
5. This and the following notes only apply when the firmware is built with
the `RESET_TO_BL31` option.
The `--data="<path-to><bl31|bl32|bl33-binary>"@<base-address-of-binary>`
parameter is used to load bootloader images into Base FVP memory (see the
"Building the Trusted Firmware" section above). The base addresses used
should match the image base addresses in `platform_def.h` used while linking
the images. The BL3-2 image is only needed if BL3-1 has been built to expect
a Secure-EL1 Payload.
6. The `-C cluster<X>.cpu<Y>.RVBAR=@<base-address-of-bl31>` parameter, where
X and Y are the cluster and CPU numbers respectively, is used to set the
reset vector for each core.
5. The `--data="<path-to><bl31/bl32/bl33-binary>"@base address of binaries`
parameter is used to load bootloader images in the Base FVP memory (see the
"Building the Trusted Firmware" section above). The base address used to
load the binaries with --data should match the image base addresses in
platform_def.h used while linking the images.
BL3-2 image is only needed if BL3-1 has been built to expect a secure-EL1
payload.
7. Changing the default value of `FVP_SHARED_DATA_LOCATION` will also require
changing the value of
`--data="<path-to><bl31-binary>"@<base-address-of-bl31>` and
`-C cluster<X>.cpu<X>.RVBAR=@<base-address-of-bl31>`, to the new value of
`BL31_BASE` in `platform_def.h`.
8. Changing the default value of `FVP_TSP_RAM_LOCATION` will also require
changing the value of
`--data="<path-to><bl32-binary>"@<base-address-of-bl32>` to the new value of
`BL32_BASE` in `platform_def.h`.
