staging: unisys: visorbus: address theoretical int overflows

Add necessary casting to several places where we were doing 32-bit
arithmetic (unsigned) to produce a 64-bit (unsigned long) result, to
prevent the theoretical possibility of a 32-bit overflow during the
arithmetic.

FYI, these are unsigned long:

ctx->param_bytes
ctx->allocbytes

These are unsigned int:

bytes
phdr->name_offset
phdr->name_length

Here is the test program demonstrating why we really need the casts:

void main()
{
unsigned int i;
unsigned long il;

printf("sizeof(int) =%dn",sizeof(i));
printf("sizeof(long)=%dn",sizeof(il));

i = (unsigned int)((((unsigned long)(1)) << 32) - 1);
printf("i                     = %un", i);
il = i+1;
printf("adding 1 withOUT cast = %lun", il);
il = (unsigned long)i+1;
printf("adding 1 WITH    cast = %lun", il);
}
[selltc@mac tmp]$ gcc x.c -o x.out
[selltc@mac tmp]$ ./x.out
sizeof(int) =4
sizeof(long)=8
i                     = 4294967295
adding 1 withOUT cast = 0
adding 1 WITH    cast = 4294967296

overflow, but moving to either timespec64 or ktime_t is preferred.

in microseconds. The algorithm slightly changes here, to avoid 64-bit

("PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected")
PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM.
