[PATCH v2] Convert CFG_SYS_UBOOT_START to Kconfig

Fri Aug 25 03:59:48 CEST 2023
Commit 65cc0e2a65d2 ("global: Move remaining CONFIG_SYS_* to CFG_SYS_*")
renamed CONFIG_SYS_UBOOT_START to CFG_SYS_UBOOT_START. Unfortunately,
this meant that the value was no longer available to the Makefile. This
caused imxrt to fail to boot. All the other boards that used this
variable were unaffected because they were using the default value
which is CONFIG_TEXT_BASE.
This commit converts CFG_SYS_UBOOT_START to Kconfig and sets the default
value to CONFIG_TEXT_BASE.

V1->V2:
- Add "and executed" to TEXT_BASE
- Reword SYS_UBOOT_START
- Reword HAVE_SYS_UBOOT_START
- Use bool as prompt
