STD_COM_FLAGS is mostly a bad name for what the drivers thinks it is.
Stop using it and pass the flags directly.
cyclades defines it as 0, so we do not assign anything to freshly
tty_port_init'ed structure.

The UPF_* flags are the correct values to use for struct uart_port
and struct old_serial_port/SERIAL_PORT_DFNS.

Build-time fixes:
- make lbeg/lend/lcount save/restore conditional on kernel entry;
- don't clear lcount in platform_restart functions unconditionally.
Run-time fixes:
- use correct end of range register in __endla paired with __loopt, not
the unused temporary register. This fixes .bss zero-initialization.
Update comments in asmmacro.h;
- don't clobber a10 in the usercopy that leads to access to unmapped
memory.

sysmem structure initialization in xt2000 platform_init is identical to
the one done in init_arch just before the call to platform_init.

Only set the register when there is at least one ibreak register,
otherwise the build fails:
arch/xtensa/kernel/head.S:105: Error: invalid register 'ibreakenable'
for 'wsr' instruction
arch/xtensa/platforms/iss/setup.c:67: Error: invalid register
'ibreakenable' for 'wsr' instruction

- reference SRs by names where possible, not by numbers;
- get rid of __stringify around SR names where possible;
- remove unneeded SR names from asm/regs.h;
- add SREG_ prefix to remaining SR names;
