[PATCH v3] imx8/ls10xx: Use a sane SYS_MALLOC_F_LEN default

[PATCH v3] imx8/ls10xx: Use a sane SYS_MALLOC_F_LEN default

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

When adding new features to imx8m boards, such as DM clock support,
the malloc area can be exhausted.

To avoid such issue, provide a reasonable default for the
SYS_MALLOC_F_LEN size.

Quoting Tom Rini:

"This seems to be an area where everyone is either:
- Kicking the value up a bit for themselves
- Having hard to figure out problems booting the platform because it's
  too small a value until they see someone else picked a larger value.

So lets raise these a bit and get some acks, please."

Applied to u-boot/master, thanks!
