Bring back FW_TEXT_START as an optional parameter to allow users
explicitly specify compile time address for loading debug symbols.
When not specified, the FW_TEXT_START is assumed to be 0.

remove FW_TEXT_START.

lib: sbi: Introduce trap context2024-03-19T06:01:22ZAnup Patelapatel@ventanamicro.com2024-03-11T09:10:12Zurn:sha1:abea949721bc635cfe39e34adc501d7be87db8ae
Club the struct sbi_trap_regs and struct sbi_trap_info a new
struct sbi_trap_context (aka trap context) which must be saved
by low-level trap handler before calling sbi_trap_handler().
To track nested traps, the struct sbi_scratch points to the current
trap context and the trap context has pointer to pervious context
of previous trap.

To track nested traps, the struct sbi_scratch needs a pointer the
current trap context so add trap_context pointer in struct sbi_context.

Over the years, no uses of sbi_trap_exit() have been found so remove
it and also remove related code from fw_base.S and sbi_scratch.h.

The same detection was done twice when setting mtvec and trap_exit.
Merging can reduce code size.
