A lot of configs has been moved to Kconfig and it ends up in ifdef mess
with no bodies. That's why remove all of them.

Enable caches by default. For now just simplify config file but it should
be read from DT or PVRs.

There is no need to use this file anymore. Include it in main config file
and simplify logic based on it.

XIP is not enabled in SPL. SPL_NOR is enabled but any macro setting with
using SYS_FLASH_BASE are wrong because it is not aligned with DM.
That's why change these macro and align them with TEXT_BASE macro.
Information should be find at run time based on DT but implementation is
not done yet.

Changes in v2:
- Rework the whole patch because SPL_NOR is enabled by default.

Remove fixed configuration and detect flash based on DT.
Also increase amount of flash sectors to 2048 because on kc705 flash has
1027 sectors.
Bank # 1: CFI conformant flash (16 x 16) Size: 128 MB in 1027 Sectors
Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x8962
Erase timeout: 4096 ms, write timeout: 2 ms
Buffer write timeout: 5 ms, buffer size: 1024 bytes
