rockchip: set malloc pool size to 0 before relocation in spl state on rk3036 based board

RK3036 only has 4kb sram, the spl code will use
3.4 ~ 3.5 kb, the last 0.5kb are used for SP and
GD, so there is no space for malloc. Also, the spl
will directly return to bootrom after dram initialized,
they never need the space for malloc.

rockchip: spl: make boot0 hook TPL safe

When building for a TPL/SPL setup (e.g. on the RK3368), we need the
TPL stage to have the extra space for for the 'Rockchip SPL name'
(i.e. 'RK33' word).  Yet, the SPL will start execution at its first
word (i.e. the first word in the SPL binary needs to be a valid
instruction).  To make things a bit more involved, CONFIG_SPL_BUILD
is defined both for the SPL and the TPL stage.

To avoid having to explicitly test for the first stage (TPL, if and
only if TPL and SPL are built, SPL otherwise), this commit modifies
the sequence to repeat the 'b reset' (instead of reserving 4 bytes
of undefined space) at the start of the boot0 hook: if overwritten
(and execution starts at the second word), the first instruction is
still a 'b reset'... if not overwritten, we start on a 'b reset' as
well.

This solution wouldn't even require the check whether we are in the
SPL/TPL build (i.e. CONFIG_SPL_BUILD), but we leave this check in for
documentation purposes.
