Drop PLATFORM_DEFAULT_MEM_START from the platform/hardware.h headers.
Provide definition of CONFIG_DEFAULT_MEM_START always, allow changing it
only in noMMU configurations when PLATFORM_WANT_DEFAULT_MEM is selected.
Change prompt and description so that it's clear that it controls
PAGE_OFFSET and PHYS_OFFSET.

config DEFAULT_MEM_START
- hex "Physical address of the default memory area start"
- depends on PLATFORM_WANT_DEFAULT_MEM
- default 0x00000000 if MMU
- default 0x60000000 if !MMU
- help
- This is the base address of the default memory area.
- Default memory area has platform-specific meaning, it may be used
- for e.g. early cache initialization.

+ prompt "PAGE_OFFSET/PHYS_OFFSET" if !MMU && PLATFORM_WANT_DEFAULT_MEM
+ default 0x60000000 if PLATFORM_WANT_DEFAULT_MEM
+ default 0x00000000
+ help
+ This is the base address used for both PAGE_OFFSET and PHYS_OFFSET
+ in noMMU configurations.
If unsure, leave the default value here.
