Introduce print_entry_point_info() function
This patch introduces a new function called 'print_entry_point_info'
that prints an entry_point_t structure for debugging purposes.
As such, it can be used to display the entry point address, SPSR and
arguments passed from a firmware image to the next one.
This function is now called in the following images transitions:
- BL1 to BL2
- BL1 to BL31
- BL31 to the next image (typically BL32 or BL33)
The following changes have been introduced:
- Fix the output format of the SPSR value : SPSR is a 32-bit value,
not a 64-bit one.
- Print all arguments values.
The entry_point_info_t structure allows to pass up to 8 arguments.
In most cases, only the first 2 arguments were printed.
print_entry_point_info() now prints all of them as 'VERBOSE'
traces.
