lcd: split splash code into its own function
lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.
Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
lcd_clear() (which is arguably not the correct name for housing such
code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
lcd_clear() too.

mx53loco: Fix boot hang during reboot stress test
Currently by running the following test:
=> setenv bootcmd reset
=> save
=> reset
, we observe a hang after approximately 20-30 minutes of stress reboot test.
Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.
MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":
"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."
According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:
"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"
So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.
With this change applied the board has gone through three days of reboot stress
test without any hang.
