board: var-som-mx8mn: Fix alloc space exhausted in SPL

After enabling some options to support EEPROM read in SPL
(CONFIG_SPL_I2C_EEPROM), the following error appears:

    alloc space exhausted

Increasing SYS_MALLOC_F_LEN from 8kB to 64kB fixes the problem.

But instead of manually increasing the value, adopt method used in
commit ce3f23404c19 ("board: bsh: imx8mn_bsh_smm_s2/s2pro: enlarge
CONFIG_SPL_SYS_MALLOC_F_LEN"):

Dropping CONFIG_SPL_SYS_MALLOC_F_LEN option allows it to be set to the
default value of CONFIG_SYS_MALLOC_F_LEN, which is set by default to 64kB
(0x10000) on i.MX8M platforms.
