Add rom_data_lookup_inline function instead of rom_data_lookup, similar to rom_func_lookup_inline. The code is moved from bootrom.c to bootrom.h, with the rom_data_lookup function changed to a simple call of rom_data_lookup_inline, similar to rom_func_lookup.

Also use this inline lookup in flash_devinfo_ptr to avoid touching a function in flash during flash programming.

Allows ROM data lookup from FLASH/RAM sensitive code
Fixes bug introduced by raspberrypi#2082 where flash_devinfo_get_cs_size would use rom_data_lookup from flash during a __no_inline_not_in_flash_func
