u-boot: config: Setting the correct ivt values

ivt base address value is computed as follows

hdr_base = entry_point – sizeof(struct imx_header);

However the value is misscalculated due to:
- the entry point is the same as the CONFIG_SYS_TEXT_BASE and
  originally has the value of 0x3f008000

- the size of the imx_header is altered when holding the attribute
  to keep it aligned to 4K

This patch moves the CONFIG_SYS_TEXT_BASE to 0x3f000800 and removes
the attribute to reflect the correct values in the ivt base address.
